Lower bound on the pseudoscalar mass in the minimal supersymmetric standard model
In the Higgs sector of the minimal supersymmetric standard model, the mass of the pseudoscalar $A$ is an independent parameter together with $\mathrm{tan}\ensuremath{\beta}\ensuremath{\equiv}{v}_{2}{/v}_{1}$. If ${m}_{A}$ is small, then the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}h+A$ is kinematically allowed and is suppressed only if $\mathrm{tan}\ensuremath{\beta}$ is small, i.e., less than one. On the other hand, …
