| dc.description.abstract | We present the results of a search for a very light CP-odd Higgs boson a01 originating from top quark decays
t?H±b?W±(*)a01b, and subsequently decaying into ?+??. Using a data sample corresponding to an integrated luminosity of 2.7??fb?1 collected by the CDF II detector in p¯p 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 a01. | es_ES |
