Signals of a Sneutrion (N)LSP at the LHC

Speaker: Brock Tweedie, Johns Hopkins University

When: February 16, 2010 (Tue), 12:30PM to 01:30PM (add to my calendar)

This event is part of the HET Seminar Series.

Abstract: While usually not considered, the sneutrino is a viable candidate for the next-to-lightest supersymmetric particle, NLSP, in supersymmetry spectra with gravitino LSP. Since the sneutrino decays invisibly, it will appear to be the true LSP at the LHC. We find that this situation can lead to very distinctive multi-lepton signals. We study these signals in detail, and demonstrate our approach on simulations incorporating backgrounds.
