Angular distribution of $Λ_{c}^{+} \to Λ_{1405/1520}^{*} (\to Σ π) ℓ^{+} ν_{ℓ}$ and implications for form factors

Kaiwen Chen, Zhi-Peng Xing, Xudong Yu +1

We study the cascade semileptonic decay $Λ_{c}^{+} \to Λ_{1405/1520}^{*} (\to Σ π) ℓ^{+} ν_{ℓ}$ using the helicity amplitude formalism, and derive the full four-body angular distribution. The…

sPHENIX measurement of Open-Charm Baryon-to-Meson Ratios in $p$ + $p$ collisions at RHIC

Xudong Yu

sPHENIX is a state-of-the-art experiment at the Relativistic Heavy Ion Collider (RHIC), dedicated to the study of heavy-flavor and jet physics. Its precision tracking system, combi…

Charmed baryon decays at BESIII

Xudong Yu

BESIII has accumulated 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ collision data in the 4.6 to 4.7 GeV energy range, corresponding to the world's largest sample of $Λ_{c}^{+} Λ ˉ_{c}^{-}$ pairs. This pape…

Search for Baryon/Lepton number violation processes at BESIII

Xudong Yu

The observed matter-antimatter asymmetry in the universe is a serious challenge to our understanding of nature. Baryon/lepton number violation (BNV/LNV) decays have been searched f…

sPHENIX measurements of heavy flavor production in $p$ + $p$ collisions

Xudong Yu

sPHENIX is the first new collider detector experiment dedicated to heavy-ion physics since the LHC began collecting data. Successfully commissioned in 2023-2024, one of its standou…
