Search for charged Higgs bosons in decays of top quarks

Abstract

We present a search for charged Higgs bosons in decays of top quarks, in the mass range $80 < m_{H^{\pm} < 155$ GeV, assuming the subsequent decay $H^{+}\to {\tau }^{+}{\nu }_{\tau }$ (and its charge conjugate). 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.
