We study the potential observation at the LHC of CP-violating effects in stop production and subsequent cascade decays, gg→t~it~i , t~i→tχ~0j , χ~0j→χ~01ℓ+ℓ− , 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 there is a significant dilution at the hadronic level after integrating over the parton distribution functions. Consequently, even for scenarios where large CP intrinsic asymmetries are expected, the measurable asymmetry is rather small. High luminosity and precise measurements of masses, branching ratios and CP asymmetries may enable measurements of the CP-violating parameters in cascade decays at the LHC. Show more
