摘要
The CP-violating effects to the subprocess gg→H+H-are studied in the mSUGRA scenario at the CERN large hadron collider,by taking into account the experimental bounds of electron and neutron electric dipole moments.The CP-violating effects in this process are related to the complex phases ofμand Af in the mSUGRA scenario.In our calculation we consider smallCP phases ofμand Af and neglect the effects of neutral Higgs boson mixing.In this case the CP effects to the process mainly come from the complex couplings of Higgs-squark-squark.We find a strong dependence of charged Higgs boson pair production rate on the complex couplings in the parameter space of minimal supersymmetric standard model.
