The properties of the $S$ -wave $D_{s} D ˉ_{s}$ bound state

Jing-Juan Qi, Zhen-Yang Wang, Zhu-Feng Zhang +1

In this work, we investigate possible bound states of the $D_{s} D ˉ_{s}$ system in the Bethe-Salpeter formalism in the ladder and instantaneous approximations. By numerically solvi…

Full analysis of CP violation induced by the decay angular correlations in four-body cascade decays of heavy hadrons

Zhen-Hua Zhang, Jian-Yu Yang, Xin-Heng Guo

The violation of the charge-parity (CP) transformation symmetry, which although has been observed in plenty of pure meson decay processes, was only confirmed just very recently by…

Nature of X(3872) from recent BESIII data: Considering the universal feature of an S-wave threshold resonance

Xian-Wei Kang, Jin-Zhe Zhang, Xin-Heng Guo

We analyze the recent data from the BESIII collaboration on the $X (3872)$ state in the $J / I ¨ I ¨ ^{+} I ¨ ^{-}$ and $D^{0} D ˉ^{0} I ¨ ^{0}$ decay channels. The quantum number and mass of the $X(3…

The $C P$ violations and branching ratios for $B_{c}^{+} \to D_{(s)}^{+} I ¨ ^{+} I ¨ ^{-} (K^{+} K^{-})$ from interference of the vector mesons in Perturbative QCD

Kun Shuai Ye, Gang LÃ¼, Na-Wang +2

Within the framework of the perturbative QCD approach utilizing $K_{T}$ factorization, we have investigated the CP violations and branching ratios in the decay processes of $B_{c}^{+…
