Polarization Probes of New Physics in Lepton-Flavor-Violating Hyperon Production from $e^{-} N \to τ^{-} Y$ 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 $τ \to ℓ d s ˉ$ transition, the corresponding decay modes involvin…

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 $Ω_{c}^{0}$ and $Ω_{b}^{-}$ , which contain two strange quarks. Using QCD light-cone sum rules (LCSRs), we calculate the…

Studying the $B^{0} \to J / ψ h_{1}$ 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 $B^{0} \to J / ψ h_{1}$ decays for the first time by using perturbative QCD approach up to the presently known next-to-leading order accuracy. The vertex c…

SKA Sensitivity to Potential Radio Emission from Dark Matter Annihilation in Ursa Major III

Peng-Long Zhang, Xiao-Jun Bi, Qin Chang +2

The recently discovered stellar system, Ursa Major III/UNIONS 1, may be the faintest and densest dwarf spheroidal satellite galaxy of the Milky Way. Owing to its close proximity an…
