Radha Mastandrea Abstract: Resonant anomaly detection is a promising framework for model-independent searches for new particles. Weakly supervised resonant anomaly detection methods compare data with a potential signal against a template of the Standard Model (SM) background inferred from sideband regions. We propose a means to generate this background template that uses a normalizing flow to create a mapping between … Read More
Abstract: I will introduce a non-relativistic limit of physics in AdS, retaining a harmonic Newtonian gravitational potential from the AdS curvature, and relate it to the spectrum and correlation functions of a dual CFT. This allows non-perturbative control for studying interesting subjects including the flat spacetime limit and resonances. Finally we will study the CFT Lorentzian inversion formula in this … Read More
Abstract: Reproducing the integer count of black hole microstates from the gravitational path integral is an important problem in quantum gravity. We will show that, by using supersymmetric localization, the gravitational path integral for 1/8-BPS black holes in N=8 supergravity reproduces the index obtained in the string theory construction of such black holes.
abstract: Light scalar fields typically develop spatially varying backgrounds during inflation. Very often they do not directly affect the density perturbations, but interact with other fields that do leave nontrivial signals in primordial perturbations. In this sense they become “missing scalars” at the cosmological collider. We study potentially observable signals of these missing scalars, focusing on a special example where … Read More
