Abstract

We examine the prospects for determining $\tan β$ from heavy Higgs scalar production in the minimal supersymmetric standard model at a future $e^{+} e^{-}$ collider. Our analysis is independent of assumptions of parameter unification, and we consider general radiative corrections in the Higgs sector. Bounds are presented for $\sqrt{s} = 500 GeV$ and 1 TeV, several Higgs boson masses, a variety of integrated luminosities and $b$ -tagging efficiencies, and in scenarios with and without supersymmetric decays of the Higgs bosons. We find stringent constraints for $3 ≲ \tan β ≲ 10$ and, for some scenarios, also interesting bounds on high $\tan β$ through ${tbH}^{\pm}$ production. These bounds imply that simple Yukawa unifications may be confirmed or excluded. Implications for soft scalar mass determination and top squark parameters are also discussed.
