We report the results of a study exclusive semileptonic decays B->pi0lnu, B->pi+lnu, B->rho0lnu, B->rho+lnu and B->omegalnu, where l represents an electron or muon. The events are tagged by fully reconstructing second B meson in event hadronic decay mode. measured branching fractions Br(B->pi0lnu) = (0.80 +- 0.08 0.04)x10^-4, Br(B->pi+lnu) (1.49 0.09 0.07)x10^-4, Br(B->rho0lnu) (1.83 0.10 0.10)x10^-4, Br(B->rho+lnu) (3.22 0.27 0.24)x10^-4, Br(B->omegalnu) =(1.07 0.16 first error is...
The widely held constructivist view of learning advocates student engagement via interactivity. Within the physics education research community, several specific interactive strategies have been developed to enhance conceptual understanding. One such strategy, Interactive Lecture Demonstration (ILD) is designed for large lecture classes and, if measured using surveys, purported provide gains up 80%. This paper reports on two different Projects over ten years. In Project 1, ILDs were...
We search for dimuon decays of a low mass particle in the ${B}^{0}\ensuremath{\rightarrow}{K}^{*0}X$ and ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{0}X$ using data sample $657\ifmmode\times\else\texttimes\fi{}{10}^{6}B\overline{B}$ events collected with Belle detector at KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. find no evidence such range from $212\text{ }\text{ }\mathrm{MeV}/{c}^{2}$ to $300\text{ lifetimes below ${10}^{\ensuremath{-}12}\text{ }\mathrm{s}$,...
We report the results of a search for rare, purely leptonic decay B^{-}→μ^{-}ν[over ¯]_{μ} performed with 711 fb^{-1} data sample that contains 772×10^{6} BB[over ¯] pairs, collected near ϒ(4S) resonance Belle detector at KEKB asymmetric-energy e^{+}e^{-} collider. The signal events are selected based on presence high momentum muon and topology rest event showing properties generic B-meson decay, as well missing energy being consistent hypothesis neutrino from decay. find 2.4 standard...
The coherent production of $\ensuremath{\pi}$ and $\ensuremath{\rho}$ mesons in ${\ensuremath{\nu}}_{\ensuremath{\mu}} ({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})$-neon charged-current interactions has been studied using the Fermilab 15-foot bubble chamber filled with a heavy Ne-${\mathrm{H}}_{2}$ mix exposed to Tevatron quadrupole triplet (anti)neutrino beam. ({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})$ beam had an average energy 80 GeV (70 GeV). From sample corresponding...
A study has been made of neutral strange particle production in ${\ensuremath{\nu}}_{\mathrm{\ensuremath{\mu}}}$Ne and \ensuremath{\nu}${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{\mathrm{\ensuremath{\mu}}}$Ne charged-current interactions at a higher energy than any previous study. The experiment was done the Fermilab Tevatron using 15-ft. bubble chamber, data sample consists 814(154) observed particles from 6263(1115)...
