A study on the rare radiative decay $B_c\to D_s^{\ast }\gamma$ in technicolor with scalars

Gongru Lu, Yigang Cao, Zhaohua Xiong +1

Applying the perturbative QCD (PQCD), we study the process $B_c\to D_s^{\ast }\gamma$ in the technicolor with a massless scalar doublet model (TCMLSM) recently presented by C. D. Caro…
