CP-Violation in Top Quark Pair Production in the Complex MSSM at Hadron Colliders

Abstract

We study possible CP violating effects due to the one loop corrections to the top quark pair production in the Complex MSSM with minimal flavor violation (MFV) at hadron colliders. We calculate the complete SUSY Electroweak and SUSY QCD corrections to the two main production mechanisms, namely: the quark-antiquark annihilation and the gluon fusion processes. At the top quark level, we study the spin-spin correlating observables that may be sensitive to the CP violating phases presented in the Complex MFV-MSSM. We present here the main results at the parton level, in particular the SUSY QCD contributions, which are the most important ones.
