Energy Distribution of the Leptons in Top Decay to Charged Higgs

Abstract

We analyze the energy distribution of the leptons coming from the top decay t\ra b\hc,\ bW^+\ra bl^+\nu. The correlation between the lepton energy distribution and the top spin may be useful for distinguishing the \hc signature from the $W$ background. Such a correlation can also be useful for disentangling the two different \hc \bar tb couplings and determining the experimental value of $\tan\beta$.Comment: talk given at the Workshop on Physics at Current Accelerators and the Supercollider, Argonne, Illinois, June, 1993, 5 pages (LATEX) + 3 figures (not included but available on request) SLAC-PUB-6354, SCIPP 93/2
