We present the results of a search in [ital [bar p]] [ital p] collisions at [radical][ital s] =1.8 TeV for the top quark decaying to a charged Higgs bosson ([ital H][sup [plus minus]]). We search for dilepton final states from the decay chain [ital t] [ital [bar t]][r arrow][ital HH] (or [ital HW], or [ital WW])+[ital b] [ital [bar b]][r arrow][ital ll]+[ital X]. In a sample of 19.3 pb[sup [minus]1] collected during 1992--93 with the Collider Detector at Fermilab, we observe 2 events with a background estimation of 3.0[plus minus]1.0 events. Limits at 95% C.L. in the (M[sub top],M[sub [ital H][sup [plus minus]]]) plane are presented. For the case [ital M][sub top][lt][ital M][sub [ital W]]+[ital M][sub [ital b]], we exclude at 95% C.L. the entire ([ital M][sub top],[ital M][sub H[plus minus]]) plane for the branching ratio [ital B]([ital H][r arrow][tau][nu]) larger than 75%. We also interpret the results in terms of the parameter tan[beta] of two-Higgs-doublet models.
