Semileptonic decay of $Λ_{b}^{0} \to Λ_{c} (2860)^{+} / Λ_{c} (2625)^{+} ℓ^{-} ν_{ℓ}$ 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 $Λ_{b}^{0} \to Λ_{c} (2860)^{+}$ and $Λ_{b}^{0} \to Λ_{c} (2625)^{+}$ using QCD light-cone sum rules, and compute the branc…

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 $Λ_{b}^{0} \to Λ_{c} (2595)^{+}$ 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 $Λ_{b}^{0} \to Λ_{c} (2595)^{+}$ , where the final charm baryon represents an excited state with spin-parity $\frac{1}{…

Study of the $B^{+} \to π^{+} (π^{+} π^{-})$ decay in PQCD Approach

Qin Chang, Lei Yang, Zhi-Tian Zou +1

Based on the fitting results of the LHCb collaboration on the contributions of various intermediate resonances to the $B^{+} \to π^{+} π^{+} π^{-}$ decay, we make systematically calcul…
