We present results of a search for the top quark decaying to a charged. Higgs boson (H) in p[bar p] collisions at [radical]s = 1.8 TeV at the Fermilab Tevatron. Using 4.1 pb[sup [minus]1] of data collected during the 1988--1989 CDF run, we have searched for evidence of t[bar t] production assuming that t[r-arrow] Hb and H[r-arrow] [tau][nu][sub [tau]]. We find no evidence for this decay and are able to exclude regions in the (m[sub t], m[sub H]) plane for different Br(H[r-arrow] [tau][nu][sub [tau]]). We also interpret these results for the two Higgs doublet(THD) model.

This paper presents the results of a search in $\bar{p}$ collisions at √s = 1.8 TeV for the toop quark decaying to a charged Higgs boson (H±).

We present results of a search for the top quark decaying to a charged. Higgs boson (H) in p{bar p} collisions at √s = 1.8 TeV at the Fermilab Tevatron. Using 4.1 pb−1 of data collected during the 1988--1989 CDF run, we have searched for evidence of t{bar t} production assuming that t→ Hb and H→??{sub?}. We find no evidence for this decay and are able to exclude regions in the (m{sub t}, m{sub H}) plane for different Br(H→ {tau}?{sub {tau}}). We also interpret these results for the two Higgs doublet(THD) model.
