摘要：

The six form factors which characterize the matrix elements of the axial vector and vector currents that occur in semileptonic LAMBDA-b --> LAMBDA-cevBAR decay are expressible, to leading order, in terms of a single function of v' v, normalized at zero recoil. We show that including terms proportional to 1/m(c), the form factors are still expressible in terms of a single function (whose normalization at zero recoil is known) and one dimensionful constant.
