SUMMARY:Searching for weakly produced supersymmetric particles using the A
 TLAS detector at the LHC. - Sarah Williams (Cambridge)

CONTACT:Susan Haines
DESCRIPTION:This seminar focuses on the search for weakly produced supersy
 mmetric particles (particularly charginos and sleptons) in the ATLAS exper
 iment at the LHC using events with exactly two reconstructed leptons.  Thi
 s analysis was first performed using the 2011 dataset and an extension bas
 ed on 2012 data was performed earlier this year. The motivation for such s
 earches will be presented\, and the analysis technique outlined. Because o
 f the low signal cross sections for weak production processes\, high backg
 round suppression is required\, and in both the 2011 and 2012 analyses the
  sensitivity is driven by signal regions based on the "stransverse mass va
 riable"\, which will be described in the seminar. Finally\, the results of
  the latest search will be presented and discussed.
