Searching for a CP-odd Higgs via a pair of gauge bosons at the LHC
  The CP-odd Higgs boson $A^0$ of the Minimal Supersymmetric Standard Model (MSSM) and Two Higgs Doublet Model (2HDM) will usually decay into the heaviest possible fermion -- antifermion pair available. The $A^0 \to VV$ decay where, $V =\gamma, Z, W^\pm$, and gluons are of particular interest as they are not allowed at tree level and hence they may offer information about the underlying new physics that enters at one loop level. In this paper all branching ratios of the CP-odd Higgs boson $A^0$ both in the MSSM and 2HDM are presented for this channel including all relevant Standard Model (SM) and MSSM particles. This discovery channel might provide an opportunity to search for a CP-odd Higgs boson at the Large Hadron Collider (LHC) and new physics beyond the Standard Model. Expressions for these decays are given in the Appendices.
