Implications of $B^+ to K^+ ubar u$ under rank-one flavour violation hypothesis
2025-04-01 09:00 - 10:00 | Salle de Sommets
Speakers: Claudio Toni
We study the implications of the observed excess at Belle-II under the assumption of Rank-One Flavour Violation, i.e. that New Physics couples to a single specific direction in flavour space. By varying this direction we perform analyses at the level of the low-energy EFT, the SMEFT, and with explicit mediators such as leptoquarks and colorless vectors. Among the various mediators, the scalar leptoquarks $tilde{R}_2$ and $S_1$ offer the best fits of the Belle-II excess, while being consistent with the other bounds. On the other hand, colorless vectors are strongly constrained by meson mixing and resonance searches. In all cases we find that a flavour alignment close to the third generation is generically preferred.

Taming projection effects in EFT of LSS analysis of DESI
2025-04-03 09:00 - 10:00 | Auditorium Vivargent (LAPTh)
Speakers: Marco Bonici (INAF-IASF Milano)
The analysis of galaxy clustering measurements from surveys like Euclid or DESI is likely to be affected by the so-called projection effects, which causes the 1D marginals of the analysis to not contain the bestfit; this is a serious issue which can potentially harm the cosmological interpretation of these analyses. In this talk I will present a few avenues to tackle this issue, either using simulation-calibrated priors, a frequentist framework, or a bayesian reparametrization approach. All of these approaches can significantly reduce the projection effects, following different strategies.
Specifically, I will show the ongoing application of these methods to current DESI DR1 data, and will compare the results among them and with the baseline DESI analysis.

L’héliocentrisme selon Copernic
2025-04-04 12:00 - 14:00 | Auditorium Vivargent (LAPP / LAPTh)
Speakers: Richard Taillet (Université de Savoie/LAPTH)
L’hypothèse d’un univers héliocentrique formulée par Nicolas Copernic en 1543, en opposition au modèle géocentrique dit « de Ptolémée » et en vigueur depuis plus d’un millénaire, marque un tournant majeur dans notre conception du monde, au point que l’expression « révolution copernicienne » est entrée dans le langage courant. Toutefois, cet épisode de l’histoire des sciences est souvent présenté d’une manière caricaturale, qui ne permet pas de saisir pleinement la proposition copernicienne, avec ses forces et ses faiblesses. Lors de ce séminaire, destiné à des physiciens et physiciennes, Richard Taillet tentera de dresser un tableau détaillé du modèle héliocentrique, des problèmes qu’il avait vocation à résoudre, des oppositions qu’il a suscitées et des alternatives qui ont été avancées pendant le siècle qui a suivi.

Zucheng Gao - Chasing parity-violating signature in large-scale structure cosmology
2025-04-08 09:00 - 10:00 | Salle de Sommets
Speakers: Zucheng Gao
Parity-violating has been found in the weak interactions. In cosmology, certain inflation mechanism can also introduce parity-violating imprints on the primordial fluctuations. Here we present theoretically how the parity-violating signature enters large-scale structure (LSS), based on Eulerian perturbation theory (EPT). We develop an effective estimator to extract parity-violating information from LSS. We test this estimator by performing both the theory calculation and the measurement on simulations. We also pin down the obstacles faced by LSS surveys before we can claim a detection of a primordial parity-violating signature.

Daniele Oriti - Late-time cosmic acceleration from Quantum Gravity
2025-04-09 14:00 - 15:00
Speakers: Daniele Oriti (Universidad Complutense de Madrid)
.
Abstract: We show how a cosmological dynamics with a late-time cosmic acceleration and an asymptotic deSitter regime can be obtained from hydrodynamics on minisuperspace, a framework generalising quantum cosmology with non-linear terms. We also show how this hydrodynamics framework can be derived from fundamental quantum gravity models within the tensorial group field theory formalism, an approach closely related to lattice quantum gravity and loop quantum gravity. If time allows, we discuss other results within the same framework, concerning emergent cosmological physics, as well as other research directions leading to it.

Defining internal symmetry in a quantum theory through the lens of topological defects has opened the door to generalised notions of symmetry. In this seminar, I will introduce such generalisations and sketch the relevant mathematical framework, before presenting explicit examples in quantum lattice models.

The Fun Side of Galaxy 4-Point Functions
2025-04-15 09:00 - 10:00 | Auditorium Vivargent (LAPTh)
Speakers: Jiamin HOU (Max Planck Institute for Extraterrestrial Physics (MPE))
Galaxy N-point function statistics provide a powerful tool for extracting non-Gaussian information. To efficiently compute N-point functions, various approaches have been proposed, including radial-angular decomposition in harmonic space and compressed statistics. In particular, the statistics involving four fields can be designed to be an effective tool for extracting parity-odd features from the field, where these odd features may originate from the beyond standard model physics. In this talk, I will discuss the application of the galaxy four-point function, the connections between different algorithms involving four fields, and the potential implications of using the galaxy four-point functions to link late-time and early-time physics.

WIMPs and New Physics Interpretations of the PTA Signal are Incompatible
2025-04-17 09:00 - 10:00 | Auditorium Vivargent (LAPTh)
Speakers: Yann Gouttenoire (Tel Aviv University)
Abstract: In order to explain the large amplitude of the nano-Hertz stochastic gravitational wave background observed in pulsar timing arrays (PTA), primordial sources must be particularly energetic. This is correlated to the generation of large density fluctuations, later collapsing into ultra-compact mini-halo (UCMHs). We demonstrate that if dark matter is made of WIMPs, then photon and neutrino fluxes from UCMHs produced by curvature peaks, first-order phase transition and domain wall interpretations of the PTA signal, exceed current bounds.

Loops in the EFT/PT of Structure Formation
2025-05-15 09:00 - 10:00 | Auditorium Vivargent (LAPTh)
Speakers: Zvonomir Vlah (Ruđer Bošković Institute and University of Cambridge)
I will discuss recent developments in cosmological perturbation theory and the effective field theory (EFT) of large-scale structure. Current galaxy surveys like DESI and Euclid provide some of the cleanest probes of the universe on large cosmological scales. While the one-loop power spectrum (the two-point correlator) remains the standardised and widely adopted theoretical tool, fully exploiting the potential of these new datasets requires extending our theoretical framework to higher loops and N-point correlators. I will outline the theoretical and computational challenges involved in going beyond the one-loop level and present recent results in the context of DESI and forthcoming Euclid data.

LIM25 - Annecy
2025-06-02 10:30 - 2025-06-06 11:50 | Laboratoire d’Annecy de Physique Théorique (LAPTh)
Line intensity mapping (LIM) is an emerging observational technique with the potential to greatly enhance our understanding of both cosmology and astrophysics. By probing the large-scale structure of the universe in three dimensions across a wide range of scales and cosmic epochs, LIM offers the ability to tackle many unresolved questions in cosmology, such as the physics of inflation, the properties of neutrinos, the nature of dark matter and dark energy, and the theory of gravity. In astrophysics, LIM observations at different wavelengths enable us to investigate various phases of the interstellar and intergalactic medium, providing valuable insights into the processes behind reionization and galaxy formation. Performing intensity mapping in different wavelengths would enable us to obtain robust detection of LIM signals and assure their cosmological/astrophysical origin, and enhance the scientific return of individual observations. Despite its promise, LIM is still a relatively young field, which naturally comes with a range of instrumental, observational, and theoretical challenges that need to be addressed. The success of LIM as a reliable probe in both astrophysics and cosmology therefore depends heavily on the collaboration of experts across these areas.

LIM25 conference, the 9th edition of a series that began in 2016 (last two at Max-Planck Institute for Astrophysics, Germany (2023), and University of Illinois, NCSA, USA (2024)), seeks to bring together specialists from various disciplines central to LIM research. The event will focus on addressing current challenges, showcasing recent advances, discussing obstacles encountered during early experiments, and exploring prospects for large-scale surveys. By fostering these interactions, the conference will help to maximize LIM’s potential as a powerful tool for both cosmology and astrophysics, while cultivating a vibrant, collaborative scientific community.

The event will be held in person and we anticipate an audience of 70–100 participants.

Physics at TeV Colliders and Beyond the Standard Model 2025
2025-06-16 13:00 - 2025-07-04 16:00 | Les Houches School of Physics
The PhysTeV workshop focuses on fundamental physics at the intersection of theory and experiment, with a particular emphasis on CERN’s LHC and high-precision quantum measurements. It addresses key challenges in the Standard Model, such as the nature of dark matter, the absence of antimatter, and the issue of electroweak naturalness. PhysTeV also seeks to advance quantum field theory and refine Standard Model predictions. By bringing together theorists and experimentalists, the workshop fosters collaboration and drives the search for new physics across particle physics and related fields.
World-leading experts are convened to tackle fundamental theoretical puzzles posed by observations such as dark matter, the disappearance of antimatter in the Universe, and the discovery of the Higgs boson. Their goal is to develop innovative techniques and strategies to uncover signals of new physics at TeV-scale particle colliders and cutting-edge experiments conducted at lower energies.
The theme of the 2025 edition is New Horizons in Physics.Registration is open!Registration deadline: 30 April 2025 12 May 2025 until filled!

3rd Training School COST Action COSMIC WISPers (CA21106)
2025-09-16 06:00 - 2025-09-19 20:30 | Auditorium Vivargent (Campus du CNRS)
Registration deadline extended until the 06/06/2025!

The COST Action CA21106 3rd Training School will be held in Annecy (France) at the LAPTh, a world-class research laboratory just 40 km away from CERN.

We will support travel and accommodation expenses of up to 30 participants.
Very likely, a visit to CERN will be organised on the 17th of September.
The goal is to start training a generation of young scientists in the interdisciplinary expertise on WISPs, ranging from theoretical and experimental approaches to multi-messenger astroparticle physics and cosmology. For this purpose, the Training School will offer lectures from experts on different aspects of WISPs physics. The School is aimed at PhD students, as well as at early-career postdocs.
The European COST Action CA21106 “Cosmic WISPers in the Dark Universe: Theory, astrophysics and experiments” is an initiative funded by the COST Association, whose goal is to study axions and other very weakly interacting slim particles (WISPs) emerging in several extensions of the Standard Model of Particle Physics. Searches for WISPs are strongly motivated by our attempts to understand the nature of the dark matter and puzzling astrophysical and particle physics observations.

Yangian symmetry, GKZ equations and integrable Feynman graphs
2025-11-01 10:00 - 11:00 | Salle des Sommets (LAPTh)
Speakers: Fedor Levkovich-Maslyuk (Centre for Mathematical Science, City St George’s, University of London)
DATE IN DISCUSSIONWe extend the powerful property of Yangian invariance to a new large class of conformally invariant multi-loop Feynman integrals. This leads to new highly constraining differential equations for them, making integrability visible at the level of individual Feynman graphs. Our results apply to planar Feynman diagrams in any spacetime dimension dual to an arbitrary network of intersecting straight lines on a plane (Baxter lattice), with propagator powers determined by the geometry. The graphs we consider determine correlators in the recently proposed “loom” fishnet CFTs. The construction unifies and greatly extends the known special cases of Yangian invariance to likely the most general family of integrable scalar planar graphs. We also relate these equations in certain cases to famous GKZ (Gelfand-Kapranov-Zelevinsky) hypergeometric operators, opening the way to using new powerful solution methods.

Public outreach talk: On Wednesday 10th December, there will be a public event from 17h until 19h, including at 18h a public outreach talk in French by Thibaut Coudarchet. This is part of “Les Mercredis du LAPP et du LAPTh”.

Registration: is open from the 8th September till the 12th November (or earlier if filled). Registration is mandatory for participation. For organisational reasons, unfortunately, we cannot accept more than about 80 participants. Therefore, each registration will be subject to approval, and confirmation will be sent. Priority will be given to experts in the field.

Contributed talks: we offer the possibility to young participants to propose a contributed talk of 20 minutes, including questions. This is done together with the registration. This call will be open from the 08th September till the 03rd October 2025, after which we will proceed with a selection.

Coffee, 3 lunches and 1 workshop dinner: those will be offered to registered participants. Attendance is asked during registration. Coffee and lunches take place at LAPTh. The workshop dinner will take place on Thursday 11th December at 19:30 at the restaurant Bleu Imperial. To reach the dinner restaurant as a group, we will leave LAPTh and catch the Bus 1 at Campus (18:41 or 18:53), stop at Montremont and walk along Avenue de France.

Accommodation: we recommend Hotel de Bonlieu, Allobroges Park Hotel or Moxy Annecy, even though many other hotels are possible in Annecy. Speakers and discussion conveners get two nights (10-12th Dec.) pre-booked and covered by us.

Travel information: nearby airports are in Geneva and Lyon. Annecy can also be reached by train (SNCF) or by bus (see below).
From Geneva airport as well as Geneva Cornavin train station, you can reach Annecy by train or by bus (272). It takes between 1:30 to 2 hours, and booking for both can be done on the Swiss train website. A faster option (45 mins), although traffic and border dependent, is by car. Other options are Flixbus (bus) or Blablacar (bus and car sharing).
From Lyon airport, you would have to take a fast tram to Lyon La Part Dieu train station. From there, you can take a train to Annecy (between 1:30 to 2 hours). Other options from Lyon are by car (1:30 hour) or again Flixbus or Blablacar.
Once at Annecy train and bus station, or from the city center, LAPTh can easily be reached by bus (e.g. with line 1, direction “Parc des Glaisins”, stop at “Campus”) following these instructions. It takes about 20 mins, and tickets can be bought with cash at the bus driver, or with a text message (SMS). SIBRA is the public transport website.
More travel information can also be found here. Travel expenses remain to be covered by participants.

Social activities: Annecy, with its lake and old city, deserves to be explored. At this time of the year, we also recommend the Christmas markets. In addition, the mountain surroundings offer ski resorts, sometimes reachable by public transport.

Disclaimer: Some registered participants have been contacted via phishing emails about their “hotel booking” or “reservation confirmation”. Please be careful, this is a scam.
