Supersymmetric enhancement of associated ZA^0 production at e^+e^- colliders

We study the associated production of the A^0 neutral CP-odd Higgs boson with a neutral gauge boson Z in high energy e^+ e^- collisions at the one loop level. We present a detailed discussion for the total cross-section predicted in the context of the Minimal Supersymmetric Standard Model (MSSM) and make a comparison with the non-SUSY Two Higgs Doublet Model (THDM). We show that the MSSM cross-section may be enhanced compared to that for the THDM.

CP-odd Higgs boson production in association with Neutral gauge boson in High-Energy $e^+e^-$ Collisions

We study the associated production of a CP-odd Higgs boson $A^0$ with a neutral gauge boson ($Z$ or photon) in high-energy $e^+ e^-$ collisions at the one-loop level in the framework of Two Higgs Doublet Models (THDM). We find that in the small $\tanβ$ regime the top quark loop contribution is enhanced leading to significant cross-sections (about a few fb), while in the large $\tanβ$ regime the cross-section does not attain observable rates.
