Higgs alignment and the top quark
In 1976, S. Weinberg and his student, E. Gildener (GW), proposed multi-Higgs models of electroweak symmetry breaking which are clas- sically scale-invariant. If this scale invariance is spontaneously broken, the […]

Cosmological first-order phase transition are said strongly supercooled when the nucleation temperature is much smaller than the critical temperature. They are typical of potentials which feature nearly scale-invariance, for which […]
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 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 […]
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 […]
