Available in PDF, EPUB and Kindle. Book excerpt: We use the heavy quark effective theory to investigate the form factors that describe the semileptonic decays of a B meson into excited daughter mesons. For an excited daughter meson with charm, a single form factor is needed at leading order, while five form factors and two dimensionful constants are needed to order 1/m(sub)c in the heavy quark expansion. For non-charmed final states, a total of four form factors are needed at leading order. For the process B ->D^(*)Xlv, four form factors are also needed at leading order.

Download or read book Excited Charm Mesons in Semileptonic B Decay and Their Contributions to a Bjorken Sum Rule written by and published by . This book was released on 1991 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has recently been shown that hadrons containing a single heavy quark exhibit a new flavor-spin symmetry of QCD. We exploit this symmetry to obtain model independent predictions for the fourteen form factors in weak decays from the ground state pseudoscalar meson P(sub)Q(sub)i of a heavy quark Q(sub)i to the low-lying positive parity excited states of a heavy quark Q(sub)j in terms of two universal functions of momentum transfer. These predictions are of interest in the study of B -> D*(sub)2(2460), D(sub)1(~2460), D(sub)1(2420), and D*(sub)0(~2420) semileptonic decays. We also discuss the connection between these results and the slope of the function Xi (which determines the B->D and B->D* transition form factors) given by a heavy quark sum rule suggested by Bjorken.

Download or read book Measurement of Semileptonic B Decays Into Orbitally-Excited Charm Mesons written by and published by . This book was released on 2008 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a study of B decays into semileptonic final states containing charged and neutral D1(2420) and D*2(2460). The analysis is based on a data sample of 208 fb−1 collected at the?(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. With a simultaneous fit to four different decay chains, the semileptonic branching fractions are extracted from measurements of the mass difference?m = m(D**)-m(D) distributions. Product branching fractions are determined to be?(B → D1°l+?{sub l}) x?(D1° → D*+?−) = (2.97 ± 0.17 ± 0.17) x 10−3,?(B+ → D*2°l+?{sub l}) x?(D*2° → D{sup (*)+}?−) = (2.29 ± 0.23 ± 0.21) x 10−3,?(B° → D1−{ell}+?{sub {ell}}) x?(D1− → D*°?−) = (2.78 ± 0.24 ± 0.25) x 10−3 and?(B° → D*2−{ell}+?{sub {ell}}) x?(D*2− → D{sup (*)0}?−) = (1.77 ± 0.26 ± 0.11) x 10−3. In addition they measure the branching ratio?(D*2 → D?°)/?(D*2 → D{sup (*)}?−) = 0.62 ± 0.03 ± 0.02.

Download or read book Exclusive Semileptonic Decays of B Mesons to Orbitally and Radial Excited D. written by and published by . This book was released on 2002 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we compute, within in the context of a relativistic quark model, the Isgur-Wise functions for exclusive semileptonic $\bar B \to X_c$ decays, where $X_c$ is any charmed mesons with total spin $J=0,1,2$ or one of their first excited states. The relevant matrix elements are computed by a direct numerical integration, in coordinate space, of the convolution of the wave function of the $B$ meson at rest and the wave function of the $X_c$ meson, boosted according with its recoil factor. Our results are compared with other predictions found in the existing literature.
