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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: We have studied semileptonic B meson decays with a P-wave charm meson in the final state using 3.29 x 10[sup 6] B[bar B] events collected by the CLEO II detector at the Cornell Electron-positron Storage Ring. We find a value for the exclusive semileptonic product branching fraction:[Beta](B[sup -][yields] D[sub 1][sup 0][ell][sup -][bar[nu]][sub[ell]])[Beta](D[sub 1][sup 0][yields] D*[sup+][pi][sup -])= (0.373[+-] 0.085[+-] 0.052[+-] 0.024)% and an upper limit for[Beta](B[sup -][yields] D*[sub 2][sup 0][ell][sup -][bar[nu]][sub[ell]])[Beta](D*[sub 2][sup 0][yields] D*[sup+][pi][sup -])

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.

This book was released on 1999-11-15 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics of heavy flavors is a very active area of research in experimental and theoretical high energy physics. A number of heavy flavor experiments at new or upgraded accelerators are just coming on line to address some of the most fundamental questions of particle physics, e.g. matter-anti-matter asymmetry (CP violation).The Seventh International Symposium on Heavy Flavor Physics focused primarily on the physics of bottom and charmed quarks, but there were also sessions on the top quark and the tau lepton. It presented a great opportunity to take stock of the field on the eve of the new era in heavy flavor physics which will be opened up by the next generation of experiments.
