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

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