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 […]

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 […]

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 […]

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: […]

Speakers: Ivano Basile (Garching, Max Planck Inst.) . Abstract: Finding reliable scale-separated vacua with no moduli in the string landscape is a considerable challenge, yet it is essential to connect string theory to our universe. Among several attempts, toroidal compactifications supported by fluxes and Casimir energy stand out for their simplicity and degree of parametric […]

Speakers: Azadeh Moradinezhad (Laboratoire d'Annecy-le-Vieux de Physique Théorique (LAPTh)) Le modèle /CDM décrit remarquablement bien l'Univers observé, mais il ne rend pas compte de l'origine des structures ni de lanature du secteur sombre. La précision croissante des observations met en évidence des tensions pouvant signaler une nouvellephysique. Dans cet exposé, je présenterai mes travaux et […]

Speakers: Zarija Lukic Ongoing and upcoming cosmology surveys aim to address some of the deepest questions in fundamental physics—from the nature of dark energy and dark matter to tests of gravity and particle physics on the largest observable scales. Interpreting these data, which probe multiple cosmic epochs and physical scales, is a formidable challenge: it […]
