Findings

Predicted branching ratios for $B_c o V A$ and $AA$ decays.

Provided form factors for $B_c o A$ transitions within the ISGW II model.

Analyzed both favored and suppressed decay modes.

Abstract

We investigate the weak decays of $B_c$ mesons in Cabibbo-Kobayashi-Maskawa favored and suppressed modes. We present a detailed analysis of the $B_c$ meson decaying to vector meson (V) and axial-vector meson (A) in the final state. We also give the form factors involving $B_c \to A$ transition in the Isgur-Scora-Grinstein-Wise II framework and consequently, predict the branching ratios of $B_c \to V A$ and $AA$ decays.
