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…

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…

Normalization of partial wave CP asymmetries in three-body decays of heavy hadrons

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

CP violation in hadronic multi-body decays has been extensively studied, and the experimental breakthrough in the heayy baryon sector was made recently. Partial-Wave CP Asymmetries…
