The Rencontres de Physique des Particules (RPP) are the annual general meeting of the French community in theoretical high-energy physics. It dwells into the deepest puzzles posed by our current understanding of the fundamental structure of matter and the history of our Universe. Aiming at pushing further the frontier of knowledge. The Laboratoire d'Annecy de […]

Speakers: Claudia Fevola (Inria-Saclay) Feynman integrals play a central role in particle physics, particularly in the theory of scattering amplitudes. A key challenge lies in identifying the values of physical parameters at which a given integral develops singularities. In this talk, I will present examples demonstrating how the interplay between algebro-geometric methods and fundamental physics […]

Speakers: Oliver Schlotterer (Uppsala Universitet) https://indico.in2p3.fr/event/35296/

Speakers: Thomas Floss (University of Vienna) Cosmology 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 […]

Speakers: Ekta Chaubey (U. Bonn) In 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 […]

Speakers: Miguel Montero (IFT Madrid) . Abstract: 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 […]

Speakers: Vivian Poulin (LUPM (CNRS & U. de Montpellier)) Over 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 […]

Speakers: Baptiste Cerclé (EPFL) Conformal 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 […]
