A Precise Determination of $\tan \beta$ from Heavy Charged Higgs Decay

Abstract

We compute the energy spectrum of charged leptons in the decay $H^{+}\to \bar{b}+(t\to bl{\nu }_l)$. The shape of the lepton spectrum obtained, and also the mean lepton energy, are sensitive to the handedness of the intermediate top quark. This sensitivity can be used to precisely determine $\tan \beta$, a fundamental parameter of two Higgs doublet models.
