LIMITS ON CHARGED HIGGS USING
CROSS SECTION MEASUREMENTS
Abstract
We present the results of a search for charged Higgs in the decay products of at the CDF II detector at the Tevatron. The search is based on the cross section measurements of
production in three exclusive decay channels: dilepton, lepton + jets and lepton + hadronic tau. Assuming the charged Higgs decays only via
, and
, and
, limits in the MSSM (mHiggs, tan(β)) plane are obtained at tree level. A model-independent analysis is introduced in which the results are independent of Higgs branching ratios. This analysis results in BR(t→Hb)<0.7 at 95%CL for 80 GeV<mHiggs<150 GeV.
