Unified study of hyperon semileptonic decays in a relativistic three-quark model

Ru-Hui Ni, Zhen-Yang Wang, Jia-Jun Wu +1

We present a unified theoretical study of semileptonic decays of ground-state octet hyperons using the relativistic three-quark model (R3QM). A key innovation of our approach is th…

Contributions of interference and non-interference components to CP asymmetries in heavy meson decays

Jing-Juan Qi, Yi-Fan Zhao, Jin-Xia Liu +3

In multi-body decays of heavy mesons, conventional CP asymmetry observables obtained by integrating over the full phase space are insensitive to the higher-order wave expansion con…

Production of $D_{s} D ˉ_{s}$ and $D D ˉ$ bound states in the $B$ decays within the Bethe-Salpeter framework

Zhen-Yang Wang, Jing-Juan Qi, Zhen-Hua Zhang +1

Within the Bethe--Salpeter framework, we investigate the production of possible $D_{s} D ˉ_{s}$ $(X_{s s ˉ})$ and $D D ˉ$ $(X_{q q ˉ})$ bound states in $B$ decays. The boun…

Direct $C P$ violation in $D^{\pm} \to I ¨ ^{\pm} I ¨ ^{+} I ¨ ^{-}$ with $a_{0}^{0} (980) - f_{0} (980)$ mixing

Shi-Ji Cao, Jing-Juan Qi, Yi-Fan Zhao +3

We investigate the direct $C P$ violation in the decay $D^{\pm} \to I ¨ ^{\pm} I ¨ ^{+} I ¨ ^{-}$ incorporating the $a_{0}^{0} (980)$ - $f_{0} (980)$ mixing mechanism. The integrated mixing intensities $\o…

The spectra of $b c b ˉ c ˉ$ tetraquark states from a diquark-antidiquark perspective

Zhen-Yang Wang, Jing-Juan Qi, Zhen-Hua Zhang +1

Within the diquark-antidiquark framework, this study investigates the masses of ground-state tetraquarks composed of heavy charm ( $c$ ) and bottom ( $b$ ) quarks and antiquarks, using…
