Av. Manohar et Mb. Wise, INCLUSIVE SEMILEPTONIC-B AND POLARIZED LAMBDA(B) DECAYS FROM QCD, Physical review. D. Particles and fields, 49(3), 1994, pp. 1310-1329
The differential decay spectrum d Gamma/dE(e)dq(2) for the semileptoni
c decay of an unpolarized hadron containing a b quark and the decay sp
ectrum d Gamma/dE(e)dq(2)d cos theta for polarized Lambda(b) decay are
computed to second order in the 1/m(b) expansion. Most of the 1/m(b)(
2) corrections have a simple physical interpretation, which is discuss
ed in detail. The implications of the results for the determination of
V-ub are discussed. The decay spectra for the semileptonic decay of h
adrons containing a c quark are also given. There is a subtlety in the
use of the equations of motion at order 1/m(b)(2) in the heavy quark
expansion which is explained.
