| Summary: | This thesis presents a measurement of the branching fraction for the exclusive semileptonic
decay B° —> D*+yTV^. This decay is essentially the decay of a b quark to a c quark
inside the meson with the release of a muon and neutrino, and it provides a very clean
signal for measuring various B meson decay properties. The data for this measurement
consist of 22.3 million BB pairs collected by the BABAR detector at the Stanford Linear
Accelerator Center in 1999-2000. The branching fraction is measured to be B(B° —>
