Description

We investigate possible CP violating effects due to one loop corrections to top-quark pair production at the LHC in the context of the complex MSSM with minimal flavor violation (MFV). We include the complete supersymmetric QCD as well as supersymmetric electroweak contributions to the top-quark pair production mechanisms, namely quark-antiquark annihilation, qq → tt, and gluon fusion, gg → tt. At the level of the top quarks, we study in detail spin-spin correlating observables that are sensitive to CP violating phases of the complex MFV-MSSM. We present results for these observables at the parton and hadron level, where we show the maximal possible contributions of the one loop MSSM corrections.
