Unraveling weak radiative hyperon decays with broken flavor symmetry
Kaiwen Chen, Lin Qiu, Jin Sun +2
We present a broken flavor analysis of weak radiative decays of spin-1/2 hyperons, incorporating current-current and electromagnetic-penguin contributions as well as charge…
Angular distribution of and implications for form factors
Kaiwen Chen, Zhi-Peng Xing, Xudong Yu +1
The paper derives the full four‑body angular distribution for the cascade semileptonic decay Λ_c^+ → Λ^*_{1405/1520}(→ Σπ) ℓ^+ ν_ℓ using helicity amplitudes, and shows how the resu…
Decoding the Amplitude Pair with Distinct CPV Phases in Charmed Baryon Decays
Zhi-Peng Xing, Jin Sun, Xiao-Gang He
In this Letter, we propose a strategy to extract information on the hierarchical amplitude pair in singly Cabibbo-suppressed (SCS) charmed baryon two-body decays, with a dominant a…
Predictions for CP violation in anti-triplet beauty baryon to charmonium decays
Jin Sun, Zhi-Peng Xing, Xiao-Gang He
Motivated by the recent 3.9 evidence for CP violation from the LHCb collaboration in decays of an anti-triplet beauty baryon to a charmonium, an octet baryon, and a pseudoscala…
Implications of recent LHCb data on CPV in b-baryon four body decays
Qi Chen, Xin Wu, Zhi-Peng Xing +1
Motivated by the recent CPV observation, we investigate the CPV of b-baryon charmless four body decays under the U-spin symmetry. However, we find that only U-spin symmetry cannot…
Probing semi-leptonic FCNC decay with new physics effects under PQCD approach
Chao-Qi Zhang, Jin Sun, Zhi-Peng Xing +1
Recently, the Belle II Collaboration reported the branching fraction with a significance of , which is a…
