Abstract: Vector-Like Leptons and Inert Scalar Triplet: Lepton Flavor Violation, $g-2$ and Collider Searches (arxiv.org) Zoom link: https://cnrs.zoom.us/j/91049381574?pwd=TDZyU3NqT0k4MFk3cUMvc0JuOURCdz09
Abstract: The von Neumann entropy is key quantity in quantum information and in the investigation of many-body models. In this talk, we will show that tools from algebraic combinatorics and from the study of time and band limiting problems can simplify its computations for systems of free fermions on graphs.
Contrary to charged lepton degeneracies which are tightly constrained by the measured baryon-to-photon ratio, the allowed values of the primordial neutrino asymmetries cover a large range. In order to study […]

Classical integrable sigma-models form an important class of two-dimensional integrable field theories. It is a long standing belief that such models define renormalisable Quantum Field Theories. In this talk, I […]
Flavourful Feebly-Interacting Particles (FIPs) in the MeV to GeV range have a strong impact on precision frontier observables ranging from rare meson decays to the lepton anomalous magnetic moments. Based […]
By considering the photon-graviton scattering amplitude at low-energy including loops from the Standard Model, I will argue how we can infer constraints on the UV behaviour of the gravitational scattering […]
In this talk, I will give a description of semi-classical gravity in terms of quantum chaos and statistical physics. I will present the OPE Randomness Hypothesis (ORH), a generalization of […]

In this talk, I will discuss various possibilities of producing dark matter in the early universe. By describing the transition between an inflationary epoch to a late time cosmology, I will […]
