Alek Bedroya – Holographic Constraints on the String Landscape

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 […]

Testing unification and the heterotic string with the axion-photon coupling

Salle des Sommets

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, […]

Geneviève Fest

Auditorium / Grande Galérie (LAPTh Annecy)

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: […]

Ivano Basile – Horror vacui: instabilities in scale-separated Casimir compactifications

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 […]
