Speakers: Nicolas CrampéI will give the definition of the Leonard pair and itsconnection with the Askey-Wilson algebra.The use of these objects is explained in the context of different areas:integrable systems, centralizer, graph theory and special functions.I will explain generalizations I am interest in.https://indico.in2p3.fr/event/31460/

Speakers: Nico Gubernari (Cambridge U., DAMTP)Rare $B$ meson decays are powerful probes for testing the Standard Model (SM). Recent measurements of several observables in $bto s mumu$ transitions have revealed tensions with the corresponding SM predictions. These tensions — or anomalies — have a significance above $3sigma$.  However, the theoretical predictions in these decays are […]

Speakers: Davide Racco (Ethz)The low-frequency part of a primordial gravitational wave spectrum generated by local physics in a wide class of phenomena (such as a phase transition), is largely fixed by causality, offering a clean window into the early Universe. The physics of low-frequency modes allows to probe in a model-independent way the Hubble rate […]
