Abstract

We present a search for charged Higgs bosons in decays of top quarks, in the mass range 80<mH±<155GeV, assuming the subsequent decay H+τ+ντ (and its charge conjugate). Using 0.9fb1 of lepton+jets data collected with the D0 detector at the Fermilab Tevatron pp¯ collider, operating at a center of mass energy s=1.96TeV, we find no evidence for a H± signal. Hence we exclude branching ratios B(tH+b)>0.24 for mH±=80GeV and B(tH+b)>0.19 for mH±=155GeV at the 95% C.L.
