Mixing-angle sensitivity of inclusive $Ξ_{b c}$ and $Ω_{b c}$ lifetimes

Hai-Yang Cheng, Chia-Wei Liu, Fanrong Xu

We study the inclusive lifetimes of $Ξ_{b c}^{+}$ , $Ξ_{b c}^{0}$ , and $Ω_{b c}^{0}$ , with emphasis on the mixing between the spin-zero and spin-one $b c$ -diquark configurations. The re…

The Negative- $Σ Σ ˉ$ Angular-Parameter Puzzle in $J / ψ$ and $ψ (2 S)$ Decays

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu

Experimental measurements of $J / ψ$ and $ψ (2 S)$ decays to octet baryon pairs reveal a negative- $Σ Σ ˉ$ puzzle in the angular distributions: $α_{Σ}^{J / ψ} < 0$ , whereas the other measure…

Study of doubly heavy baryon lifetimes

Hai-Yang Cheng, Chia-Wei Liu

We study the lifetimes and inclusive semileptonic decay widths of doubly heavy baryons within the framework of heavy quark expansion. Our analysis includes next-to-leading-order co…

Puzzles in charmed baryon semileptonic decays with $S U (3)_{F}$ flavor symmetry and lattice inputs

Chao-Qiang Geng, Chia-Wei Liu, Sheng-Lin Liu

Recent measurements of charmed-baryon semileptonic decays signal large tensions between experiment and theory, including $S U (3)_{F}$ analyses and lattice-quantum chromodynamics simul…

Strange Quark Electric Dipole Moment withTopological Anomalies

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu +1

We introduce an anomaly-based framework to probe quark electric dipole moments in exclusive hadronic final states produced in $e^{+} e^{-}$ annihilation. Chern-Simons-induced anomalous…

Topological quantization of vector meson anomalous couplings

Chao-Qiang Geng, Chia-Wei Liu, Yue-Liang Wu

We identify an overlooked Wess--Zumino--Witten structure in the hidden-local-symmetry~(HLS) formulation of vector mesons. The newly identified term generically leads to the topolog…
