Abstract: The ratios $R(D^{(*)})$ are defined as the $tau/mu$ ratio of the branching fractions of exclusive semileptonic $B to D^{(*)}$ decays. They are a powerful test of Lepton Flavour Universality, one of the pillars of the SM, and are determined by the hadronic Form Factors (FFs) describing the $B to D^{(*)}$ decays. Through the novel Dispersive Matrix (DM) approach, […]
The goal of identifying the Standard Model of particle physics and its extensions within string theory has been one of the principal driving forces in string phenomenology. Recently, the incorporation of artificial intelligence in string theory and certain theoretical advancements have brought to light unexpected solutions to mathematical hurdles that have so far hindered progress […]
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 […]
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 […]

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. […]
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 […]
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 […]
