Using 0.9 fb$^{-1}$ of lepton+jets data collected with the D0 detector at the Fermilab Tevatron $p/bar{p}$ collider, operating at a center of mass energy $/sqrt{s}=1.96$ TeV, we find no evidence for a $H^{/pm}$ signal. Hence, we exclude branching ratios $B(t /to H^+b) > 0.24$ for $m_{H^{/pm}=80$ GeV, and $B(t /to H^+b) > 0.19$ for $m_{H^{/pm}=155$ GeV, at the 95% C.L.
