Tue, Mar 7, 2017, 2:00 pm

Supersymmetry (SUSY) is a well-motivated theory beyond the standard model (SM)which provides solutions to several open questions in particle physics, e.g. the cancellation of quadratically divergent loop corrections to the mass of the Higgs boson.
In R-Parity conserving SUSY, the lightest SUSY particle (LSP) is stable and can be a viable...

High Energy Theory Seminar-"BTZ/CFT" -Raman Sundrum- Uni. of Maryland

High Energy Theory Seminar - Matthew Headrick, Brandeis University - "Causality, holography, and entanglement entropy"

Mon, Feb 17, 2014, 2:30 pm to 3:30 pm
The covariant holographic entanglement entropy formula expresses the entropy of a given region in terms of the area of a certain spacelike surface in the bulk. In holographic models of thermalization involving gravitational collapse, it has been observed that this extremal surface probes the region behind the event horizon.
