High Energy Theory Seminar

April 03, 2015 | 1:45pm - 3:00pm

In this talk I review the holographic dual of an entangled pair of a quark and an anti-quark. The bulk dual on the Poincare patch is a string with an Einstein-Rosen bridge on its worldsheet. String solutions will be discussed that correspond to...

Solutions of string/M theory with low energy supersymmetry breaking generically have light moduli fields whose masses are of order the supersymmetry breaking scale. These fields -- whose expectation values parametrise the size and shape of the...

Physics Group Meeting

March 25, 2015 | 1:30pm - 3:00pm

I will review progress and questions originating from an attempt to quantize pure gravity on AdS3 by using canonical quantization in a "constrain first" approach. Questions will outnumber answers.

We review the issue of "state dependence" of bulk to boundary maps for the black hole interior in AdS/CFT. We argue that this is necessary not only for single sided black holes but also for the eternal black hole. We resolve some potential...

The LHC data are severely constraining natural theories of electroweak symmetry breaking.

An important part of the constraints comes from the fact that typically the partners of the top quark in carry color and can be profusely produced at hadron...

Informal HET Seminar

A spatially extended excess of ~1-3 GeV gamma rays has been detected from the region surrounding the Galactic Center, consistent with the emission expected from annihilating dark matter. Recent improvements in the analysis techniques have found this...
