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

We explore the CP violation in the charged Higgs production associated with a top quark at the LHC within the context of the MSSM. The supersymmetric loop corrections to the tbH vertex lead to the CP violating asymmetry of the cross section in the pp → gb → tH process. We find that a large CP violation is possible if the charged Higgs boson is heavy enough and the CP asymmetry could be detected at the LHC. PACS numbers: Typeset using REVTEX
