Abstract The production process for the charged Higgs boson associated with the W boson via gluon-gluon fusion at the CERN large hadron collider (LHC) in the minimal supersymmetric standard model (MSSM) is investigated with one-loop diagrams of both quarks and scalar quarks. We find the contribution from the scalar quark loops can be comparable with those from quark loop diagrams and could decrease or enhance the cross section substantially in some parameter space. The results show that this cross section can be about 45 fb with our chosen input parameters at the CERN LHC. The analysis of the p/sub T/ distribution shows that the line shapes partly depend on the virtual scalar quark contributions. The numerical analysis of their production rates is also carried out in the minimal supergravity (MSUGRA) scenario. We find that the supersymmetric contributions can reach +56% of the total cross section in the MSUGRA-inspired MSSM. (26 refs).
