AdS4 black holes and 3d gauge theories

Regular Seminar Alberto Zaffaroni (Milan Bicocca)

at:
13:15 KCL
room G01 Norfolk Building
abstract:

One of the great success of string theory is the microscopical explanation of the entropy of a class of asymptotically flat black holes. Much less is known about asymptotically AdS black holes in four dimensions or higher. In this talk I explain how to derive the entropy of a class of asymptotically AdS supersymmetric black holes in four dimensions using holography. The counting of black hole micro-states is related to a counting of states in the dual 3d gauge theory which can be explicitly performed using localization.

The master space of N=1 gauge theories

Exceptional Seminar Alberto Zaffaroni (Milano (Bicocca) and INFN)

at:
14:30 IC
room Blackett 630
abstract:

I discuss some aspects of the full moduli space of N=1 supersymmetric gauge theories, focusing on those arising on D-branes at Calabi-Yau singularities. Of particola importance is the full moduli space for one brane, called the master space. I discuss its geometrical properties and its relation with the uncovering of hidden symmetries and the counting of BPS states of the gauge theory.

Conformal Field Theories, BPS states and Geometry

Triangular Seminar Alberto Zaffaroni (Univerisy di Milano-Bicocca and INFN, Italy)

at:
16:30 QMW
room Queen Mary
abstract:

I discuss some aspects of the conformal field theories obtained by placing D3 branes at conical singularities focusing on the rich interplay between the properties of the gauge theories and the geometry of the internal manifold. I discuss in particular the role of baryons, a character for counting all BPS baryonic operators and its geometrical interpretation.
