Abstract

We present the results of a search for a very light CP-odd Higgs boson a10 originating from top quark decays t→H⊃±b→W⊃± (⊃*)a10b, and subsequently decaying into τ⊃+τ⊃-. Using a data sample corresponding to an integrated luminosity of 2.7fb⊃-1 collected by the CDF II detector in pp̄ collisions at 1.96TeV, 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 20GeV/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 a10. © 2011 American Physical Society.
