SUMMARY:3rd Training School COST Action COSMIC WISPers (CA21106)
DESCRIPTION:Registration deadline extended until the 06/06/2025!\n \nThe 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.\n \nWe will support travel and accommodation expenses of up to 30 participants.  \nVery likely\, a visit to CERN will be organised on the 17th of September.\nThe 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.\nThe 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.\n \nhttps://indico.in2p3.fr/event/35550/

SUMMARY:LIM25 - Annecy
DESCRIPTION: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.\n \nLIM25 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.\n \nThe event will be held in person and we anticipate an audience of 70–100 participants.\n \n🎉 REGISTERATION AND ABSRACT SUBMISSION NOW OPEN! 🎉 Please follow the links on the left or below.\n \n🚨 SCAM ALERT: Please be aware of fraudulent emails\, e.g.\, from olivia@cermix.org or michael@funds-indico.org or lodging@conferencecare.org\, claiming to offer hotel bookings or registration confirmations.

SUMMARY:Loops in the EFT/PT of Structure Formation
DESCRIPTION:Speakers: Zvonomir Vlah (Ruđer Bošković Institute and University of Cambridge)\n 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.\n \n \nhttps://indico.in2p3.fr/event/36159/

SUMMARY:WIMPs and New Physics Interpretations of the PTA Signal are Incompatible
DESCRIPTION:Speakers: Yann Gouttenoire (Tel Aviv University)\nAbstract: 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.\nhttps://indico.in2p3.fr/event/35590/

SUMMARY:The Fun Side of Galaxy 4-Point Functions
DESCRIPTION:Speakers: Jiamin HOU (Max Planck Institute for Extraterrestrial Physics (MPE))\nGalaxy 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.\nhttps://indico.in2p3.fr/event/35591/

SUMMARY:Introduction to generalised symmetries
DESCRIPTION:Speakers: Clément Delcamp (IHES)\nDefining 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.\nhttps://indico.in2p3.fr/event/35727/

SUMMARY:Daniele Oriti - Late-time cosmic acceleration from Quantum Gravity
DESCRIPTION:Speakers: Daniele Oriti (Universidad Complutense de Madrid)\n.\nAbstract: 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.\nLink: Zoom\nAnLy: https://sites.google.com/view/anlystringsandfields\n \n \nhttps://indico.in2p3.fr/event/35680/

SUMMARY:Zucheng Gao - Chasing parity-violating signature in large-scale structure cosmology
DESCRIPTION:Speakers: Zucheng Gao\nParity-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.\n \n \nhttps://indico.in2p3.fr/event/36088/

SUMMARY:L’héliocentrisme selon Copernic
DESCRIPTION:Speakers: Richard Taillet (Université de Savoie/LAPTH)\nL’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.\n \nhttps://indico.in2p3.fr/event/35666/

SUMMARY:Taming projection effects in EFT of LSS analysis of DESI
DESCRIPTION:Speakers: Marco Bonici (INAF-IASF Milano)\nThe 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.\nSpecifically\, 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.\nhttps://indico.in2p3.fr/event/35426/

SUMMARY:Implications of $B^+ to K^+  ubar u$ under rank-one flavour violation hypothesis
DESCRIPTION:Speakers: Claudio Toni\nWe 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.\nhttps://indico.in2p3.fr/event/36029/

SUMMARY:A probabilistic approach to Toda Conformal Field Theories
DESCRIPTION:Speakers: Baptiste Cerclé (EPFL)\nConformal invariance is a feature that arises for a large class of models of statistical physics at criticality. To address the issue of understanding the conformal field theory (CFT) thus defined\, Belavin-Polyakov-Zamolodchikov designed in 1984 a general method for solving such a theory\, dubbed conformal bootstrap. However there is a large class of models\, such as the critical three-states Potts model\, that enjoy in addition to conformal invariance an enhanced level of symmetry called higher-spin symmetry. Capturing this feature led to the introduction by Zamolodchikov of the notion of W-algebras\, which are Vertex Algebras containing the Virasoro algebra.\n \nIn this talk we will explain how this higher-spin symmetry manifests itself for Toda CFTs\, generalizations of Liouville CFT that enjoy this higher level of symmetry. Namely in a first part we will explain how probability theory allows to define rigorously such models. We will then explain how this symmetry manifests itself within this probabilistic framework and describe some of its implications\, such as the computation of a family of correlation functions of the theory.\nhttps://indico.in2p3.fr/event/35896/

SUMMARY:New Physics from the “Hubble Tension”
DESCRIPTION:Speakers: Vivian Poulin (LUPM (CNRS & U. de Montpellier))\nOver the last decade\, measurements of the expansion rate of the universe today\, H0\, made with cepheid-calibrated SN1a have become increasingly discrepant with the value predicted from the ΛCDM model when fit to CMB data. After a brief review of the experimental situation\, I will show the potential implications of this “Hubble tension” for new physics. I will argue that it points to some new mechanism at play in the pre- recombination universe (i.e.\, z > 1000)\, rather than a new dynamical effect at late-time (i.e. 0 < z < 1). I will discuss some model-independent implications of the Hubble tension that can help shed light on its origin.\nhttps://indico.in2p3.fr/event/35427/
