Received 15 November 1993; published in the issue dated 28 March 1994
We present results of a search for the top quark decaying to a charged Higgs boson (H+) in p p¯ collisions at √s =1.8 TeV at the Fermilab Tevatron. Assuming that H+→τντ is the dominant H+ decay mode, we exclude regions of the (mH+,mt) plane for values of the branching ratio, B(H+→τντ)=0.5, 0.75, and 1.0. We interpret the results in terms of the parameter tan β in the two-Higgs-doublet model.
