SUMMARY:Moving cosmological data analysis forward with differentiable forward models
DESCRIPTION:Speakers: Thomas Floss (University of Vienna)\nCosmology is about to receive a large influx of a variety of observational data\, providing a promising avenue for addressing some of the most critical questions in fundamental physics. In this seminar\, I will give a brief introduction to some of the concepts used in standard cosmological data analysis.I will then discuss some recent work on developing more optimal methods of extracting cosmological information from data using differentiable forward models\, with the goal of maximizing the scientific potential of cosmological surveys.\nhttps://indico.in2p3.fr/event/35725/

SUMMARY:New frontiers of Feynman Integral Computations: Mathematical Structures in Phenomenology
DESCRIPTION:Speakers: Ekta Chaubey (U. Bonn)\nIn this talk\, I will discuss how to advance the mathematical understandingof multi-loop\, multi-leg\, and multi-scale Feynman integrals and to bridgethe gap between the mathematical framework of scattering amplitudes andtheir phenomenological applications. I will highlight their broad relevance\,not only in achieving groundbreaking predictions for LHC observations butalso in extending their impact beyond elementary particle physics. Forinstance\, these computations play a crucial role in the precise calculationof bound-state observables and have contributed to breakthroughs ingravitational wave research.\nhttps://indico.in2p3.fr/event/35573/

SUMMARY:Miguel Montero - The DGKT scenario and the Weak Gravity Conjecture
DESCRIPTION:Speakers: Miguel Montero (IFT Madrid)\n.\nAbstract: I will discuss how generic quantum corrections lift the moduli space of BPS branes in 4d N=1 scale-separated solutions like DGKT. This means that there is a tension between this scenario and the WGC for membranes\, which demands the existence of an exactly extremal brane. Similar tensions exist in any 4d N=1 scenario not protected by a parity symmetry\, and I will mention some examples.\nLink: Zoom\nAnLy: https://sites.google.com/view/anlystringsandfields\n \n \nhttps://indico.in2p3.fr/event/35506/

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/

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/
