Query: Testing the left-handedness of the b \to c transition   We analyse the spin structure of inclusive semileptonic b \to c transitions
and the effects of non-standard model couplings on the rates and the spectra.
The calculation includes the {\cal O} (\alpha_s) corrections as well as the
leading non-perturbative ones.
