Abstract
We search for a light Higgs boson A(0) in the radiative decay Upsilon(3S) -> gamma A(0), A(0) -> tau(+) tau(-), tau(+) -> e(+) nu(e)(nu) over bar (tau) or tau(+) -> mu(+) nu(mu)(nu) over bar (tau) . The data sample contains 122 X 10(6) Upsilon(3S) events recorded with the BABAR detector. We find no evidence for a narrow structure in the studied tau(+) tau(-) invariant mass region of 4.03 < m(tau+ tau-) < 10: 10 GeV= c(2). We exclude at the 90% confidence level (C.L.) a low-mass Higgs boson decaying to tau(+) tau(-) with a product branching fraction B(Upsilon(3S) -> A(0)) B(A(0) -> tau(+) tau(-)) > (1.5 - 16) X 10(-5) across the m(tau+ tau-) range. We also set a 90% C. L. upper limit on the tau(+) tau(-) decay of the eta(b) at B(eta(b) -> tau(+) tau(-)) < 8%.
