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±[superscript (*)]a10b, and subsequently decaying into tau+tau-. Using a data sample corresponding to an integrated luminosity of 2.7 fb[superscript -1] collected by the CDF II detector in pp[over-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 a10.
