Measurement of Inclusive RadiativeB-Meson Decays with a Photon Energy Threshold of 1.7 GeV
Limosani, A.,Aihara, H.,Arinstein, K.,Aushev, T.,Bakich, A. M.,Balagura, V.,Barberio, E.,Bay, A.,Belous, K.,Bischofberger, M.,Bondar, A.,Bozek, A.,Brač,ko, M.,Browder, T. E.,Chang, P.,Chao, Y.,Ch American Physical Society 2009 Physical Review Letters Vol.103 No.24
<P>Using 605 fb(-1) of data collected at the Upsilon(4S) resonance we present a measurement of the inclusive radiative B-meson decay channel, B-->X(s)gamma. For the lower photon energy thresholds of 1.7, 1.8, 1.9, and 2.0 GeV, as defined in the rest frame of the B meson, we measure the partial branching fraction and the mean and variance of the photon energy spectrum. At the 1.7 GeV threshold we obtain the partial branching fraction BF(B-->X(s)}gamma)=(3.45+/-0.15+/-0.40)x10(-4), where the errors are statistical and systematic.</P>
Measurement of|Vub|from Inclusive Charmless SemileptonicBDecays

<P>We present the partial branching fraction for inclusive charmless semileptonic B decays and the corresponding value of the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-ub vertical bar, using a multivariate analysis method to access similar to 90% of the B -> X(u)l nu phase space. This approach dramatically reduces the theoretical uncertainties from the b-quark mass and nonperturbative QCD compared to all previous inclusive measurements. The results are based on a sample of 657 X 10(6) B (B) over bar pairs collected with the Belle detector. We find that Delta B(B -> X(u)l nu; p(l)*(B) > 1.0 GeV/c) = 1.963X(1 +/- 0.088(stat) +/- 0.081(syst)) X 10(-3). Corresponding values of vertical bar V-ub vertical bar are extracted using several theoretical calculations.</P>

We search for lepton-flavor and lepton-number-violating τ decays into a lepton (@?= electron or muon) and two charged mesons (h,h<SUP>'</SUP>=π<SUP>+/-</SUP> or K<SUP>+/-</SUP>) using 854 fb<SUP>-1</SUP> of data collected with the Belle detector at the KEKB asymmetric-energy e<SUP>+</SUP>e<SUP>-</SUP> collider. We obtain 90% confidence level upper limits on the τ→@?hh<SUP>'</SUP> branching fractions in the range (2.0-8.4)x10<SUP>-8</SUP>. These results improve upon our previously published upper limits by factors of about 1.8 on average.
