Supersymmetric QCD and CP-violation effects in ttZ{sup 0} production at the LHC

We investigate the NLO QCD and the CP-violation effects in ttZ{sup 0} production at the LHC in the minimal supersymmetric standard model (MSSM). Our calculation shows that the total NLO QCD correction in the framework of the CP-conserving MSSM significantly improves the scale uncertainty at the lead...

Zusammenfassung:We investigate the NLO QCD and the CP-violation effects in ttZ{sup 0} production at the LHC in the minimal supersymmetric standard model (MSSM). Our calculation shows that the total NLO QCD correction in the framework of the CP-conserving MSSM significantly improves the scale uncertainty at the leading order, and the contribution from the pure supersymmetric QCD (pSQCD) correction can exceed -8% with the restrictions of 90 GeV
