SUSY Effects in $t\overline{t}$ Production in the CP-Violating MSSM at the LHC

ORAL

Abstract

We investigate possible CP violating effects due to one loop MSSM corrections to top-quark pair production at the LHC. We include supersymmetric QCD as well as supersymmetric electroweak contributions to the top-quark pair production mechanisms, namely quark-antiquark annihilation, $q\overline{q}\rightarrow t\overline{t}$, and gluon-gluon fusion, $gg\rightarrow t\overline{t}$. 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 MSSM.
