On the Effectiveness of an Opportunistic Traffic Management System for Vehicular Networks

7 pages, 5 postscript figures, submitted to Physical Review LettersWe search for hadronic decays of a light Higgs boson (A0) produced in radiative decays of an Upsilon(2S) or Upsilon(3S) meson, Upsilon --> gamma A0. The data have been recorded by the BABAR experiment at the Upsilon(3S) and Upsilon(2S) center of mass energies, and include (121.3 \pm 1.2) x 10^6 Upsilon(3S) and (98.3 \pm 0.9) x 10^6 Upsilon(2S) mesons. No significant signal is observed. We set 90% confidence level upper limits on the product branching fractions B(Upsilon(nS)-->gamma A0) x B(A0-->hadrons) (n=2 or 3) that range from 1 x 10^{-6} for an A0 mass of 0.3 GeV/c^2 to 8 x 10^{-5} at 7 GeV/c^2

Search for lepton flavor violating decays tau(+/-)-> l(+/-)omega

A search for lepton flavor violating decays of a tau to a lighter-mass charged lepton and an omega vector meson is performed using 384.1 fb(-1) of e(+)e(-) annihilation data collected with the BABAR detector at the Stanford Linear Accelerator Center PEP-II storage ring. No signal is found, and the upper limits on the branching ratios are determined to be B(tau(+/-) --> e(+/-)omega) mu(+/-)omega) < 1.0 x 10(-7) at 90% confidence level

Study of resonances in exclusive B decays to (D)over-bar((*))D((*))K

We present a study of resonances in exclusive decays of B mesons to (D) over bar (DK)-D-(*)-K-(*). We report the observation of the decays B ->(D) over bar D-(*)(s1)+(2536) where the D-s1(+)(2536) is reconstructed in the (DK+)-K-*0 and (D*+KS0) decay channels. We report also the observation of the decays B ->psi(3770)K where the psi(3770) decays to (D) over bar D-0(0) and D-D+. In addition, we present the observation of an enhancement for the (D) over bar D-*0(0) invariant mass in the decays B ->(D) over bar (DK)-D-*0-K-0, at a mass of (3875.1(-0.5)(+0.7)+/- 0.5) MeV/c(2) with a width of (3.0(-1.4)(+1.9)+/- 0.9) MeV (the first errors are statistical and the second are systematic). Branching fractions and spin studies are shown for the three resonances. The results are based on 347 fb(-1) of data collected with the BABAR detector at the PEP-II B factory
