Abstract

In the Minimal Supersymmetric Standard Model (MSSM), the masses of the charged Higgs boson ( $H^{\pm}$ ) and the CP-odd scalar ( $A$ ) are related by $M_{H^{+}}^{2} = M_{A}^{2} + m_{W}^{2}$ . Furthermore, because the coupling of $W^{-}$ - $A$ - $H^{+}$ is fixed by gauge interaction, the tree level production rate of $q q ˉ^{'} \to W^{\pm*} \to A H^{\pm}$ depends only on one supersymmetry parameter --the mass ( $M_{A}$ ) of $A$ . We show that to a good approximation this conclusion also holds at the one-loop level. Consequently, this process can be used to distinguish MSSM from its alternatives (such as a general two-Higgs-doublet model) by verifying the above mass relation, and to test the prediction of the MSSM on the product of the decay branching ratios of $A$ and $H^{\pm}$ in terms of only one single parameter -- $M_{A}$ .
