Abstract

We investigate in detail the A⁰Z⁰ associated production process pp → A⁰Z⁰+X within the framework of the minimal supersymmetric standard model (MSSM) at the CERN Large Hadron Collider (LHC), considering both contributions from 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 A⁰Z⁰ associated production subprocesses in the MSSM at the LHC, and analyse the dependences of the total cross section on neutral CP-odd Higgs boson mass m_A and tanβ in the mSUGRA scenario. We find that the contribution from loop mediated gluon fusion subprocess can be competitive with that from the Drell-Yan subprocess in some parameter space.
