Semileptonic Decays of B Mesons Into Excited Charm Mesons:LeadingOrder and 1/m(sub)c Contributions(sub)c Con

PDF Version Also Available for Download.

Description

We use the heavy quark effective theory to investigate the form factors that describe the semileptonic decays of a B meson into excited daughter mesons.For an excited daughter meson with charm, a single form factor is needed at leading order, while five form factors and two dimensionful constants are needed to order 1/m(sub)c in the heavy quark expansion.For non-charmed final states, a total of four form factors are needed at leading order.For the process B ->D^(*)Xlv, four form factors are also needed at leading order.
