<P>We report a measurement of the ratio R(D*) = B((B) over bar (0) -> D*(+)tau(-)(nu) over bar (tau))/B((B) over bar (0) -> D*(+)l(-)(nu) over bar (l))where l denotes an electron or a muon. The results are based on a data sample containing 772 x 10(6) B (B) over bar pairs recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. We select a sample of B-0(B) over bar (0) pairs by reconstructing both B mesons in semileptonic decays to D*(-/+)l(+/-). We measure R(D*) = 0.302 +/- 0.030(stat) +/- 0.011(syst), which is within 1.6 sigma of the Standard Model theoretical expectation, where the standard deviation sigma includes systematic uncertainties. We use this measurement to constrain several scenarios of new physics in a model-independent approach.</P>

<P>Using a data sample of 980 fb(-1) of e(+)e(-) annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy e(+)e(-) collider, we report the results of a study of the decays of the Omega(0)(c) charmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the Omega(0)(c) into Omega(-)pi(+)pi(0), Omega(-)pi(+)pi(-)pi(+), Xi K--(-)pi(+)pi(+), and Xi K-0(-)pi(+), as well as the first measurements of the branching fractions of the Omega(0)(c) into Xi(-)(K) over bar (0)pi(+), Xi(0)(K) over bar (0), and Lambda(K) over bar (0)(K) over bar (0), all with respect to the Omega(-)pi(+) decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay Omega(0)(c) -> Sigma+K-K-pi(+).</P>

<P>Using data collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider, we measure the energy dependence of the e(+)e(-) -> h(b)(nP)pi(+)pi(-) (n = 1, 2) cross sections from thresholds up to 11.02 GeV. We find clear gamma(10860) and gamma(11020) peaks with little or no continuum contribution. We study the resonant substructure of the gamma(11020) -> h(b)(nP)pi(+)pi(_) transitions and find evidence that they proceed entirely via the intermediate isovector states Z(b)(10610) and Z(b)(10650). The relative fraction of these states is loosely constrained by the current data: The hypothesis that only Z(b)(10610) is produced is excluded at the level of 3.3 standard deviations, while the hypothesis that only Z(b)(10650) is produced is not excluded at a significant level.</P>

<P>With the full data sample of 772 x 10(6) B (B) over bar pairs recorded by the Belle detector at the KEKB electron-positron collider, the decay (B) over bar -> D+ tau(-)(nu) over bar (tau) is studied with the hadronic tau decays tau(-) -> pi(-)nu(tau) and tau(-) -> rho(-)nu(tau). The tau polarization P-tau(D*) in two-body hadronic tau decays is measured, as well as the ratio of the branching fractions R(D*) = B((B) over bar -> D*tau(-) (nu) over bar (tau))/B((B) over bar -> D*l(-) (nu) over bar (l),where l(-) denotes an electron or a muon. Our results, P-tau (D*) = - 0.38 +/- 0.51(stat)(+0.21)(-0.16) (syst) and R(D*) = 0.270 +/- 0.035(stat)(+0.028)(-0.025)(syst), are consistent with the theoretical predictions of the standard model. The polarization values of P-tau(D*) > +0.5 are excluded at the 90% confidence level.</P>
