Quasi-two-body decays $B_c\to D^{\ast }h\to D\pi h$ in the perturbative QCD

Yan-Chao Zhao, Zhi-Qing Zhang, Zi-Yu Zhang +2

In this work, we investigate the quasi-two-body decays $B_c\to D^{\ast }h\to D\pi h$ with $h=(K^0,{\pi }^0,\eta ,{\eta }^{\prime })$ using the perturbative QCD(PQCD) approach. The description of final st…
