Book Description
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.

Book Description
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.

Book Description
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 -])

Book Description
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.
