Measuring Arg($V_{ub}$) in $B\to K\pi$
Autor: Würthwein, Frank, Gaidarev, Peter
It has previously been shown that a measurement of Arg$(V_{ub})=\gamma$ can be obtained from a triangle construction using ${\cal B}(B^0\to K^+\pi^-)$, ${\cal B}(\bar{B^0}\to K^-\pi^+)$, ${\cal B}(B^\pm\to K^0_s\pi^\pm)$, and ${\cal B}(B^\pm\to \pi^\

Autor: Alexander, J, Baker, R, Bebek, C, Berger, B, Berkelman, K, Bloom, K, Boisvert, V, Cassel, D, Crowcroft, D, Dickson, M, von Dombrowski, S, Drell, P, Ecklund, K, Ehrlich, R, Foland, A, Gaidarev, P, Galik, R, Gibbons, L, Gittelman, B, Gray, S, Hartill, D, Heltsley, B, Hopman, P, Kandaswamy, J, Kim, P
Using a 73.6 pb-1 data sample of Y(2S) events collected with the CLEO II detector at the Cornell Electron Storage Ring, we have investigated the hadronic transitions between the Y(2S) and the Y(1S). The dipion transition Y(2S)→Y(1S)π+π was studie

Search for B 0→π 0π 0 decay
Autor: Asner, D, Eppich, A, Hill, T, Morrison, R, Briere, R, Chen, G, Ferguson, T, Vogel, H, Gritsan, A, Alexander, J, Baker, R, Bebek, C, Berger, B, Berkelman, K, Blanc, F, Boisvert, V, Cassel, D, Drell, P, Duboscq, J, Ecklund, K, Ehrlich, R, Gaidarev, P, Gibbons, L, Gittelman, B, Gray, S
We have searched for the charmless hadronic decay of B 0 mesons into two neutral pions. Using 9.13 fb -1 taken at the Y(45) with the CLEO detector, we obtain an improved upper limit for the branching fraction B(B 0 → π 0π 0)

Precise measurement of B0 - B̄0 mixing parameters at the Υ(4S)
Autor: Behrens, B, Ford, W, Gritsan, A, Roy, J, Smith, J, Alexander, J, Baker, R, Bebek, C, Berger, B, Berkelman, K, Blanc, F, Boisvert, V, Cassel, D, Dickson, M, Drell, P, Ecklund, K, Ehrlich, R, Foland, A, Gaidarev, P, Gibbons, L, Gittelman, B, Gray, S, Hartill, D, Heltsley, B, Hopman, P
We describe a measurement of B0 - B̄0 mixing parameters exploiting a method of partial reconstruction of the decay chains B̄ → D(* ±)π(±) and B̄ → D(* ±) ρ (±). Using 9.6 x 106BB̄ pairs collected at the Cornell Electron Storage Ring, we

First observation of B̄→D(*) ρ′-, ρ′-→ωπ

We report on the observation of B̄→D*π+π-π-π 0 decays. The branching ratios for D*+ and D*0 are (1.72±0.14±0.24)% and (1.80±0.24±0.27)%, respectively. Each final state has a a D*ωπ- component, with branching ratios (0.29±0.03±0.04)% an

Evidence of New States Decaying into Xi(*)(c)pi
Autor: Alexander, J, Baker, R, Bebek, C, Berger, B, Berkelman, K, Boisvert, V, Cassel, D, Crowcroft, D, Dickson, M, von Dombrowski, S, Drell, P, Ecklund, K, Ehrlich, R, Foland, A, Gaidarev, P, Gibbons, L, Gittelman, B, Gray, S, Hartill, D, Heltsley, B, Hopman, P, Kreinick, D, Lee, T, Liu, Y, Meyer, T
Using 13.7 fb(-1) of data recorded by the CLEO detector at Cornell Electron Storage Ring, we report evidence of two new charmed baryons: one decaying into Xi(0')(c)pi(+) with the subsequent decay Xi(0')(c)-->Xi(0)(c)gamma, and its isospin partner dec

Observation of B → φK and B → φK
Autor: Briere, R, Chen, G, Ferguson, T, Vogel, H, Gritsan, A, Alexander, J, Baker, R, Bebek, C, Berger, B, Berkelman, K, Blanc, F, Boisvert, V, Cassel, D, Drell, P, Duboscq, J, Ecklund, K, Ehrlich, R, Gaidarev, P, Gibbons, L, Gittelman, B, Gray, S, Hartill, D, Heltsley, B, Hopman, P, Hsu, L
An overview is given on the first significant measurements of exclusive charmless hadronic decays B → φK and B → φK*. The measured branching fractions lie in the range of theoretical predictions.
