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 […]

Le LAPP et le LAPTh reçoivent à Annecy la section 29 du CNU pour la session de printemps 2025.   Logements: Nous recommandons les logements situés à proximité de la ligne de bus n°1, tels que l'hôtel de Bonlieu ou le Moxy Annecy (ex-Best Western International). A proximité immédiate du LAPP et LAPTh se trouve également, […]

Speakers: Stanislav Pakuliak Algebraic Bethe ansatz is reviewed on example of the ferromagnetic spin-chain XXX Heisenberg model.The monodromy matrix action to the off-shell Bethe vectorsis explained and the coproduct property of these vectors is shown. https://indico.in2p3.fr/event/36093/

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 […]

This is the 6th instance of the in-person AnLy meetings between neighboring institutions (IP2I Lyon, LAPTh Annecy, LPENSL Lyon) on string and field theory topics. It will take place at IP2I Lyon, on the 22nd May 2025. The room will be "Salle Croix Rousse" on the 3rd floor.   Travel: Options between Lyon and Annecy […]

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 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 […]
