CP violation induced by neutral meson mixing interference

Yin-Fa Shen, Wen-Jie Song, Qin Qin

We propose a new kind of CP violation effect -- the double-mixing CP asymmetry -- in a type of cascade decays that involves at least two mixing neutral mesons in the decay chain. I…

$D_{s}^{*} \to ϕ$ helicity form factors and the exclusive weak decays

Shan Cheng, Yao-hui Ju, Qin Qin +1

The decay width of the $D_{s}^{*}$ meson is dominated by the electromagnetic mode $D_{s}^{*} \to D_{s} γ$ , and it is thus the longest-lived charged vector meson. In light of this poi…
