Maths HEP Lunchtime Seminars: Anomalies and Partition Functions

Presented by Stefan Theisen, MPI Potsdam

26 May 2015 14:00 in CM101

The partition function of superconformal field theories on spheres
are given by the Kaehler potential on their moduli space. I will present a
simple proof of this fact based on Weyl anomalies of supersymmetric
CFT's, which I will discuss in the first part of the talk. In the second part
I will show how their structure, combined with supersymmetry, allows for
a simple (re)derivation of the above stated result.

(This is based on work in progress with J. Gomis, Z. Komargodski
and S. Schwimmer.)
