摘要

We investigate in detail the A(0)Z(0) associated production process pp-->A(0)Z(0)+X within the framework of the minimal supersymmetric standard model (MSSM) at the CERN Large Hadron Collider (LHC), considering contributions from both the Drell-Yan and gluon fusion subprocesses. We focus on the deviations from the general two-Higgs-doublet model (2HDM) arising in the MSSM. We also discuss the contributions of the two A(0)Z(0) associated production subprocesses in the MSSM at the CERN LHC and analyze the dependences of the total cross section on neutral CP-odd Higgs boson mass m(A) and tan beta in the MSUGRA scenario. We find that the contribution from the loop mediated gluon fusion subprocess can be competitive with that from the Drell-Yan subprocess in some parameter space.
