Title: Search for a Very Light CP-Odd Higgs Boson in Top Quark Decays from pp-bar; Collisions at √s = 1.96 TeV

Abstract

We present the results of a search for a very light CP-odd Higgs boson a 1 0 originating from top quark decays t→H ±b → W ±(*)a 1 0b, and subsequently decaying into τ +τ -. Using a data sample corresponding to an integrated luminosity of 2.7 fb -1 collected by the CDF II detector in pp-bar collisions at 1.96 TeV, we perform a search for events containing a lepton, three or more jets, and an additional isolated track with transverse momentum in the range 3 to 20 GeV/c. Observed events are consistent with background sources, and 95% C.L. limits are set on the branching ratio of t→H ±b for various masses of H ± and a 1 0.
