Constraints on the charged Higgs sector from the CDF Top quark data

Abstract

The top quark data in the lepton plus $\tau$ channel offers a viable probe for the charged Higgs boson signal. We have analysed the recent Collider Detector at Fermilab (CDF) data in this channel to obtain a significant limit on the $H^{\pm }$ mass in the large $\tan \beta$ region.
