Description
The rare decays of the $B_c$ meson induced by the flavour changing neutral current $c \to u$ transition are strongly suppressed by the Glashow-Iliopoulos-Maiani mechanism in SM. Therefore, they exhibit sensitivity to new physics effects, as long as the impacts from long-distance contributions can be controlled. The difficulty is to get rid of these hadronic effects. I will present a study of such effects in radiative $B_c$ transitions both to $B$ and to the axial-vector $B_1^{\prime}$ mesons, aiming to determine which channel offers better potential for probing new physics.
