Quasi-two-body decays $B_c^{+}\to \ddot{I}{‡}_{c0,c1}[\ddot{I}(K^{\ast })\to ]\ddot{I}€\ddot{I}€(K\ddot{I}€)$ in the PQCD approach

Jun Deng, Xian-Qiao Yu

We study the quasi-two-body decays $B_c^{+}\to \ddot{I}{‡}_{c0,c1}[\ddot{I}(K^{\ast })\to ]\ddot{I}{€}^{+}\ddot{I}{€}^0(K^0\ddot{I}{€}^{+})$ in the perturbative QCD framework at leading order. The $\ddot{I}€\ddot{I}€$ and $K\ddot{I}€$ pairs are produce…
