Rare $W \to B_{c} + I^^{3}$ decay up to the NNLO and NLL accuracy in QCD

Xin-Qiang Li, Ya-Dong Yang, Yu-Dong Zhang +1

We perform a detailed theoretical study of the rare radiative decay of the $W$ boson into a $B_{c}$ meson and an on-shell photon. The decay amplitude is described by two independent…

Electromagnetic and hadronic decay of fully heavy tetraquark

Wen-Long Sang, Tao Wang, Yu-Dong Zhang +1

In this study, we compute the electromagnetic and hadronic decay widths of the S-wave fully heavy tetraquark $T_{4 Q}$ ( $Q = c$ or $b$ ) at lowest order in $I^\pm_{s}$ and $v$ , in the frame…
