摘要：

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 tan beta regime, the top quark loop contribution is enhanced leading to significant cross-sections (about a few fb), while in the large tan beta regime the cross-section does not attain observable rates.
