QCD sum rule studies on the $ss s ˉ s ˉ$ tetraquark states with $J^{P C} = 1^{+-}$

Er-Liang Cui, Hui-Min Yang, Hua-Xing Chen +2

We apply the method of QCD sum rules to study the structure $X$ newly observed by the BESIII Collaboration in the $ϕ η^{'}$ mass spectrum in 2.0-2.1 GeV region in the $J/ψ\righta…

A possible partner state of the $Y (2175)$

Hua-Xing Chen, Cheng-Ping Shen, Shi-Lin Zhu

We study the $Y (2175)$ using the method of QCD sum rules. There are two independent $ss s ˉ s ˉ$ interpolating currents with $J^{P C} = 1^{--}$ , and we calculate both their diag…

$B_{s, d}^{*} \to μ^{+} μ^{-}$ and its impact on $B_{s, d} \to μ^{+} μ^{-}$

Guang-Zhi Xu, Yue Qiu, Cheng-Ping Shen +1

The decay of $B_{s, d}^{*} \to μ^{+} μ^{-}$ ~ and its impact on $B_{s, d} \to μ^{+} μ^{-}$ is studied here. The $μ^{+} μ^{-}$ decay widths of vector mesons $B_{s, d}^{*}$ are about a factor of 700 la…

Enhanced breaking of heavy quark spin symmetry

Feng-Kun Guo, Ulf-G. Meißner, Cheng-Ping Shen

Heavy quark spin symmetry is useful to make predictions on ratios of decay or production rates of systems involving heavy quarks. The breaking of spin symmetry is generally of the…

Quest for precision in hadronic cross sections at low energy: Monte Carlo tools vs. experimental data

S. Actis, A. Arbuzov, G. Balossini +53

We present the achievements of the last years of the experimental and theoretical groups working on hadronic cross section measurements at the low energy e+e- colliders in Beijing,…
