Semileptonic decay of $I^_{b}^{0} \to I^_{c} (2860)^{+} / I^_{c} (2625)^{+} ℓ^{-} I^½_{ℓ}$ within QCD light-cone sum rules

Hui-Hui Duan, Jia-Bao Feng, Feng-Mei Liu +1

In this work, we calculate the transition form factors for the weak decays $I^_{b}^{0} \to I^_{c} (2860)^{+}$ and $I^_{b}^{0} \to I^_{c} (2625)^{+}$ using QCD light-cone sum rules, and compute the b…

Search for Light Dark Matter in Rare Meson Decays

Ze-Kun Liu, Ying Li, Biao-Feng Hou +1

Current dark matter direct detection experiments have low sensitivity to sub-GeV dark matter. In this work, we demonstrate that rare $B$ and $K$ meson decays with missing energy in…

Form factors of $I^_{b}^{0} \to I^_{c} (2595)^{+}$ within light-cone QCD sum rules

Hui-Hui Duan, Yong-Lu Liu, Qin Chang +1

In this work, we calculated the form factors of the weak decay process $I^_{b}^{0} \to I^_{c} (2595)^{+}$ , where the final charm baryon represents an excited state with spin-parity $\frac{1…
