Abstract
We study the associated production of a CP-odd Higgs boson A(0) with a neut ral 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 th at in the small tan beta regime, the top quark loop contribution is enhance d leading to significant cross-sections (about a few fb), while in the larg e tan beta regime the cross-section does not attain observable rates.
