251. Uniquess of Black Hole Space-Times

Jay Armas

The talk will be based on the preprint: http://arxiv.org/abs/0911.4654

252. Canonical quantization of non-linear sigma models

Johan Källén

3/25/10, 2:20 PM

I will introduce the "Chiral de Rham complex" and discuss its interpretation as the formal Hamiltonian quantization of the supersymmetric non-linear sigma model.

254. Chiral de Rham complex on special holonomy manifolds

Joel Ekstrand

3/25/10, 3:00 PM

253. New results in target space geometry of non-linear sigma models

Malin Göteman

3/25/10, 3:20 PM

Recent work on N=(2,2) non-linear sigma models with only semi-chiral fields will be discussed. Imposing additional N=(4,4) supersymmetry gives constraints on the target space geometry which we analyze. This is done both in the special case of linear transformations and 4-dimensional target space, as well as in the general case.

261. On thermodynamics of N=6 superconformal Chern-Simons theory

Mikael Smedbäck

3/26/10, 12:20 PM

Recently, great progress has been made on understanding the field theory side of the AdS(4)/CFT(3) duality. The so-called ABJM theory, which is an N=6 superconformal Chern-Simons theory, has been conjectured to describe the world-volume theory on an arbitrary number of M2-branes. We discuss thermal properties of ABJM theory, by computing quantum corrections to the free energy. We find...

266. General Semi-Direct Gauge Mediation

Gabriele Ferretti

3/26/10, 4:20 PM

From 0912.0743: We give a general formulation of semi-direct gauge mediation of supersymmetry breaking where the messengers interact with the hidden sector only through a weakly gauged group. Using this general formulation, we provide an explicit proof that the MSSM gaugino masses are vanishing to leading order in the gauge couplings. On the other hand, the MSSM sfermion masses have,...

271. The Perfect Atom: Bound States of Super-QED

Thomas Klose

3/27/10, 12:20 PM

We derive the spectrum of supersymmetric hydrogen-like atoms. A difference between these perfect atoms and non-supersymmetric ones is the absence of hyperfine structure. This is in accordance with strong coupling results using AdS/CFT
