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 […]
Prof. Anamaria Font (Central University of Venezuela) is a renowned string theorist whose career has recently been recognised thanks to the L’Oréal-UNESCO International Award "For Women in Science" (see here and here). At an early stage of her career (1987-1989), Anamaria has also been a postdoc in LAPTh, Annecy, France. It is thus our pleasure […]
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 […]

Speakers: Erwan Allys (LPENS Paris) New statistical descriptions related to the so-called Scattering Transform recently obtained attractive results for several astrophysical applications. These statistics share ideas with convolutional neural networks, but do not require to be learned, allowing for very efficient characterization of non-Gaussian processes from a very small amount of data. In this talk, […]
Speakers: Diego Guadagnoli (LAPTh Annecy), Ludovico Vittorio (LAPTh, Université Savoie Mont-Blanc and CNRS, Annecy, France) Teacher: Balasubramanian Ananthanarayan (Anant), Bangalore, Indian Inst. Sci. Language: English Summary The course is placed at the interface between particle physics and mathematical physics. It is addressed to PhD-level students, and aims at introducing, in a self-contained way, fundamental concepts […]
Speakers: Jakob Moritz (CERN) . Abstract: The simplest cosmology compatible with the accelerated expansion of our universe is de Sitter space. Yet, more than 25 years after the discovery of ``dark energy’’, concrete de Sitter vacua of string theory have remained elusive. In this talk I will present the first fully concrete string compactifications that yield, […]
Speakers: Paolo Creminelli (ICTP, Trieste) The coefficients of the operators of an effective field theory (EFT) are constrained to satisfy certain inequalities, under the (mild) assumption that the UV completion satisfies general requirements of causality and unitarity. I discuss the extension of these ideas to theories where the Lorentz symmetry is spontaneously broken, as it […]
