https://www.youtube.com/watch?v=c6_RbJS8CoM&list=PL0NRmB0fnLJQAnYwkpt9PN2PBKx4rvdup&index=14&t=2s Abstract: We will overview the program of geometrically engineering four dimensional supersymmetric QFTs as compactifications of six dimensional SCFTs. In particular we will discuss how strong coupling phenomena in four dimensions, such as duality and emergence of symmetry, can be better understood in such geometric constructions.

In this talk I will argue that standard tools of holography can be used to describe fully non-perturbative microscopic models of cosmology in which a period […]

https://www.youtube.com/watch?v=jnWI9sCfAi0&list=PL0NRmB0fnLJQAnYwkpt9PN2PBKx4rvdup&index=11&t=2s Abstract: The CDF collaboration recently reported a new precise measurement of the W boson mass MW with a central value significantly larger than the SM prediction. We explore the effects of including this new measurement on a fit of the Standard Model (SM) to electroweak precision data. We characterize the tension of this new measurement […]

This talk will be an elementary review of some of these developments, based on: https://arxiv.org/abs/2204.03045

Speaker: Linhao Li (ISSP, U Tokyo) Title: Boundary conditions and LSM anomalies of conformal field theories in 1+1 dimensions Abstract: In this talk, we will study a relationship between conformally invariant boundary conditions and anomalies of conformal field theories (CFTs) in 1+1 dimensions. For a given CFT with a global symmetry, we consider symmetric gapping […]

Speaker: Seth Koren (University of Chicago) Title: Baryon Minus Lepton Number BF Theory for the Cosmological Lithium Problem Abstract: The cosmological lithium problem—that the observed primordial abundance is lower than theoretical expectations by order one—is perhaps the most statistically significant anomaly of SM+ ΛCDM, and has resisted decades of attempts by cosmologists, nuclear physicists, and […]
