Branching ratios of the Bc meson decaying to pseudoscalar and axial-vector mesons

We study Cabibbo-Kobayashi-Maskawa favored weak decays of B-c mesons in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. We present a detailed analysis of the B-c meson decaying to a pseudoscalar meson (P) and an axial-vector meson (A). We also give the form factors involving the B-c -> P/A transition in the ISGW II framework and consequently predict the branching ratios of B-c -> PA decays.
