Registration deadline extended until the 06/06/2025!   The COST Action CA21106 3rd Training School will be held in Annecy (France) at the LAPTh, a world-class research laboratory just 40 km away from CERN.   We will support travel and accommodation expenses of up to 30 participants.   Very likely, a visit to CERN will be organised on the 17th […]

Le CPTGA vous invite à sa 16ème "Journée de Physique Théorique". Le but de ces journées est de permettre des échanges entre physicien.ne.s théoricien.ne.s de Grenoble/Annecy travaillant dans des domaines très variés. Il est à la fois question de comprendre de la belle science et de découvrir le travail des collègues locaux. Le thème de […]

Speakers: Fedor Levkovich-Maslyuk (Centre for Mathematical Science, City St George’s, University of London) DATE IN DISCUSSIONWe extend the powerful property of Yangian invariance to a new large class of conformally invariant multi-loop Feynman integrals. This leads to new highly constraining differential equations for them, making integrability visible at the level of individual Feynman graphs. Our […]

This 3 days workshop aims at gathering string theorists and cosmologists to discuss recent developments on the timely topics of: Dark energy (cosmological constant or dynamical) Hubble tension and early dark energy models Inflation and CMB Cosmological correlators considering both observational constraints (including DES, DESI results, prospects from Euclid, LSST, and CMB observations) as well […]

Speakers: Samuel GARRATT (Princeton University) Studies of entanglement in the ground states of many-body systems have provided insights into the relation between spatial correlations, low-energy spectral properties, and the computational resources required to describe a system. We know much less about entanglement in thermal equilibrium. This is because, at finite temperature, spatial correlations can be […]

Speakers: Alek Bedroya (Princeton University) . Abstract: I will discuss scale separation in top-down string theory constructions of AdS vacua, focusing on proposals based on compactifications on Ricci-flat manifolds such as DGKT and KKLT. I will then present a general argument that the putative CFT duals of such scale-separated AdS vacua cannot emerge as infrared […]

Speakers: Mario Reig Lopez (Cern) The topological nature of axion couplings to gauge bosons offers unique opportunities to obtain information about the UV limit of the SM. I will discuss why the discovery of an axion-like particle above the QCD line would rule out grand unified theories and the perturbative heterotic string. Based on 2206.07053, […]

On the occasion of her retirement, a workshop to celebrate Geneviève Bélanger's contributions to research, group building, and mentoring activities. A tentative timetable is now available. Note that in addition to the scheduled review talks, there will be two "open mic" sessions open to all participants for their personal recollection, anecdotes, etc. To join by Zoom: […]
