Low-Scale SUSY Breaking: Cosmology & Collider Signals

Speaker: Matt Reece, Harvard University

When: September 26, 2011 (Mon), 12:30PM to 01:30PM (add to my calendar)
Location: PRB 595

This event is part of the HET Seminar Series.

Abstract::

In this talk, I will discuss some phenomenology associated with low-scale breaking of supersymmetry (as in models of gauge mediation). I will argue that, without fine-tuning, low-scale supersymmetry breaking is associated with light moduli fields that cause severe cosmological problems. I will explain how physics related to the strong CP problem might help solve these problems, favoring a particular SUSY-breaking scale. I will also discuss some distinctive collider signals arising in such scenarios, with long-lived neutral particles, which are currently being searched for at the LHC.
