Detecting the polarization in decays to probe hadronic loop effect
Qi Huang, Jun-Zhang Wang, Rong-Gang Ping +1
In this work, we propose that detecting the polarization information of can be as good test of the role of hadronic loop effect on these decays. Our result…
Cross sections of e+e- --> gamma VV and e+e- --> gamma gamma V
K. Zhu, C. Z. Yuan, R. G. Ping
Cross sections of the e+e- annihilation into one photon plus two vector mesons, such as J/psi rho, J/psi phi, and rho phi at the center of mass energy \sqrt{s}=10.58GeV are calcula…
Study of X(1812) as a Molecular State
Hong Chen, Rong-Gang Ping
We investigate the decay and the production mechanism of the resonance X(1812) recently observed in the $\jp\toγX(1812), X(1812)\toωϕ$ at BESII. The decay widths of …
Rescattering effects of baryon and antibaryon in heavy quarkonium decays
Hong Chen, Rong-Gang Ping
Rescattering effects of baryon and antibaryon in heavy quarkonium decays are investigated by studying their angular distributions. The rescattering amplitudes are phenomenologicall…
On the structure of the pi pi invariant mass spectra of the Upsilon(4S)-->Upsilon(1S,2S) pi^+ pi^- decays
Feng-Kun Guo, Peng-Nian Shen, Huan-Ching Chiang +1
We perform a model-independent analysis for recently reported data of the invariant mass spectra in the decays and point out that there does exist…
Productions of X(1835) as baryonium with sizable gluon content
Gui-Jun Ding, Rong-Gang Ping, Mu-Lin Yan
The X(1835) has been treated as a baryonium with sizable gluon content, and to be almost flavor singlet. This picture allows us to rationally understand X(1835) production in …
S wave Kπscattering and effects of κin J/ψ\to {\bar K}^{*0}(892)K^+π^-
Feng-Kun Guo, Rong-Gang Ping, Peng-Nian Shen +2
wave scattering is studied using a chiral unitary approach (ChUT) taking into account coupled channels. With the amplitudes derived from the lowest order chiral Lagrangian…
Heavy Quarkonium π^+π^- Transitions and a Possible b\bar{b}q\bar{q} State
F. -K. Guo, P. -N. Shen, H. -C. Chiang +1
transitions of heavy quarkonia, especially the decay process, are revisited. In the framework of the Chiral Unitary Theory (ChUT), the wave …
