Semileptonic decay of double strangeness heavy flavor baryons

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

This paper investigates the double strangeness heavy flavor baryons $I^c ◯_{c}^{0}$ and $I^c ◯_{b}^{-}$ , which contain two strange quarks. Using QCD light-cone sum rules (LCSRs), we calculate th…

Polarization Probes of New Physics in Lepton-Flavor-Violating Hyperon Production from $e^{-} N \to I ¨ ^{-} Y$ Scattering

Xin-Shuai Yan, Zhen-Qing Hu, Qin Chang +1

While charged lepton-flavor-violating tau decays to strange mesons provide powerful probes of the underlying $I ¨ \to ℓ d s ˉ$ transition, the corresponding decay modes involvi…

Studying the $B^{0} \to J / I ¨ h_{1}$ decays with $h_{1} (1170) - h_{1} (1415)$ mixing in the perturbative QCD approach

Qin Chang, De-Hua Yao, Xin Liu

In this paper, we study the $B^{0} \to J / I ¨ h_{1}$ decays for the first time by using perturbative QCD approach up to the presently known next-to-leading order accuracy. The vertex…
