# Recent progress on two-dimensional gauged linear sigma models

## by Wolfgang Lerche (CERN), Boris Samuel Pioline (CERN)

Monday, 7 October 2013 from to (Europe/Zurich)
at CERN ( 4-2-011 - TH common room )
 Description We shall review two recent papers [arXiv:1308.2157] (by J. Halverson, H. Jockers, J. M. Lapan, D. R. Morrison) and [arXiv:1308.2438] (by K. Hori, M. Romo) where new localization techniques are used to gain improved understanding of the Kahler moduli space and central charge function in two-dimensional sigma models with (2,2) supersymmetry.
