Abstract: For this journal club meeting I will comment on a recent paper by Albert and Rastelli (https://arxiv.org/abs/2203.11950) in which they apply modern S-matrix bootstrap techniques to the old problem of solving QCD in the large N limit. In particular, they derive universal bounds for the EFT of massless pions and find that the allowed […]
Star forming galaxies (SFGs) are powerful factories of high-energy cosmic rays. Their star formation rate (SFR) is a key physical property characterizing both the total energy budget and the transport conditions of such particle populations. Tight correlations are in fact observed between the SFR and the non-thermal radio and gamma-ray luminosity of several SFGs. I […]

Recent Advances in Quantum Integrable Systems
The standard model of cosmology currently allows for three types of geometries for our Universe (Euclidean, spherical or hyperbolic), each of these types corresponding to a set of different (multiconnected)-topologies. Among these geometries, Newton’s theory of gravity is only defined on the Euclidean one. Still, extending the validity of this theory to the two other […]
This 1-day workshop aims at gathering in Annecy the local string and quantum field theory community for fruitful exchanges on active research topics. Those include: Bootstrap Swampland program and string phenomenology Supergravity and Exceptional Field Theories Participating institutions are mainly LPENS (Lyon), IP2I (Lyon), LAPTh (Annecy), CERN (Meyrin), UNIGE (Geneva) and EPFL (Lausanne). Young […]
Speakers: Christopher Eckner (CNRS, LAPTh) Abstract:I will present three recent papers advancing our understanding of astrophysics and cosmology. The covered papers are:I) arXiv:2304.0607: "The Image of the M87 Black Hole Reconstructed […]
Speakers: Pedro de la Torre Luque (Stockholm University)The creation of antiparticles in the Galaxy has been discussed as a potential signal of exotic production mechanisms such as primordial black hole […]
Speakers: Gilles Parez (CRM, Montréal)Entanglement and separability are two opposite yet intertwined notions in quantum mechanics. A quantum state is said to be entangled if it is not separable, and […]
