The local Callan-Symanzik equation describes the response of a quantum field theory to local scale transformations in the presence of background sources. The consistency conditions associated with this anomalous equation can be used to derive...

Light new particles with masses well below the GeV-scale are an often considered and plausible extension of the Standard Model. In this talk I will present new results on dark photons, a massive vector boson kinetically mixed with the photon. The...

Classical conformal blocks appear in the limit c->infinity of the Virasoro conformal blocks. Classical conformal blocks have close relationship to monodromy of the second order differential equations with regular singularities. I will discuss...

I will discuss how to compute Entanglement Renyi Entropies for two dimensional holographic CFTs using AdS_3 handlebody solutions. Some simplifying assumptions are made. The answer I find is consistent with the Ryu-Takayanagi prediction for...

The electron edm is an important constraint on extensions to the Standard Model such as supersymmetric models. ACME is closing in on a more sensitive measurement of this moment, profiting from the huge electric field within the ThO molecule.
