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…

The Negative- $I^£ I^ˉ £$ Angular-Parameter Puzzle in $J / I ¨ $ and $I ¨ (2 S)$ Decays

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

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

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…

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…

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…

Potential of discovering $I^_{cc}^{+}$ in $I^_{b}$ decays

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu +2

We propose to search for $I^_{cc}^{+}$ in the decay $I^_{b} \to I^_{cc}^{+} D^{-}$ , which serves as a tagged and reconstructible source of $I^_{cc}^{+}$ , providing an experimentally clean en…
