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.

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.

The authors present a search for t[r-arrow] bH[sup+] in t[bar t] candidate events at D0 based on two methods. The first seeks a deficit in signal relative to expectations from the standard model (SM). Such a deficit would imply the presence of a non-SM decay of the top quark. This search involves the full data sample of[approx] 110 pb[sup[minus]1] of p[bar p] collisions at[radical]s= 1.8 TeV, collected with the D0 detector. The second method looks for charged Higgs decays to[tau] leptons (and associated neutrinos), and is based on a 62 pb[sup[minus]1] subset of the aforementioned data sample.
