Measurement of CP Violation in Stop Cascade Decays at the LHC

Abstract

We study the potential observation at the LHC of CP-violating effects in stop production and subsequent cascade decays, gg → t̃it̃i, t̃i → tχ̃j , χ̃j → χ̃1ll, within the Minimal Supersymmetric Standard Model. We study T-odd asymmetries based on triple products between the different decay products. There may be a large CP asymmetry at the parton level, but… (More)
