Semileptonic Decays: The Heavy Daughter Quark Limit

Abstract

We have calculated the rate of the decay b -> clv to second order in alpha_s in the limit that the b and c quarks have equal masses. The results here confirm recent calculations done in the opposite limit where the c-quark is much lighter than the b-quark.
