Endpoints of invariant mass distribution in SUSY particle decays into massive particles
arXiv:1004.4819
Abstract
Kinematic limits on an invariant mass distribution of bc-pairs for a three-step decay chain A -> bB -> bcC involving all massive particles are found. It is shown that an application of these limits to a stop quark production at the LHC could reduce significantly Standard Model background contribution.
