SEMINAR:Emerging Jets From a Dark Sector

October 10 2014, 2:30pm - Seminar room

Speaker: Pedro Schwaller (CERN)

Abstract : I will discuss a few reasons to go beyond minimal dark matter models, and some theoretical ideas that motivate us to consider a QCD-like dark sector.

One characteristic signature of such dark sectors are "emerging jets" that can be reconstructed in the calorimeter but leave few hits in the inner trackers. We propose a new strategy to search for these emerging jets, using their "trackless" feature to discriminate from QCD background. Compared to ordinary multi-jet resonance searches, the sensitivity can be increased by four orders of magnitude or more.
