An unquenched calculation of the form factor for B → D∗ln is needed to improve the determination of |Vcb|. The MILC lattices, computed with a 2+1 improved staggered action for the light quarks, are well suited to this purpose. The relevant staggered chiral perturbation theory (SChPT) must be known in order to correctly account for the "taste" breaking discretization effects associated with the staggered quarks to NLO in 1/mD ∗. This SChPT calculation is presented.
