Study of $B_c\to J/\ddot{I}ˆ(a_1(1260)$, $b_1(1235)$, $a_2(1320)$, $K_2^{\ast }(1430))$ decay with a perturbative QCD approach

Yun Zhao, Xian-Qiao Yu

Motivated by systematic observations of $B_c$ decays at LHCb, we analyze $B_c^{+}\to J/\ddot{I}ˆ(A,T)$ decays (where $A$ denotes axial-vector mesons $a_1(1260{)}^{+}$, $b_1(1235{)}^{+}$, and $T…
