Determining SUSY particle masses at LHC

PDF Version Also Available for Download.

Description

If supersymmetry (SUSY) exists at the electroweak scale, it should be east at the LHC to observe deviations from the Standard Model (SM) such as an excess of events with multiple jets plus missing energy E{sub T} or with like-sign dileptons {ell}{sup {+-}}{ell}{sup {+-}} plus E{sub T}. Determining SUSY masses is more difficult because each SUSY event contains two missing lightest SUSY particles {tilde {chi}}{sub 1}{sup 0}, and there are not enough kinematic constraints to determine the momenta of these. This note describes two possible approaches to determining SUSY masses, one based on a generic global variable and the other ... continued below
