CP violation in associated charged Higgs boson production with a single top at the LHC

Abstract

We explore the CP violation in the charged Higgs production associated with a top quark at the LHC in the MSSM. The supersymmetric phases of gaugino masses and trilinear $A$ terms lead to a CP violating asymmetry of the cross section in the $pp\to gb\to t{H}^{\pm }$ process through loop corrections to the $tb{H}^{\pm }$ vertex. We find that a CP violation more than 10 % is possible if the charged Higgs boson is heavy enough.
