Hadronic cross section of annihilation at bottomonium energy region
Xiang-Kun Dong, Xiao-Hu Mo, Ping Wang +1
The Born cross section and dressed cross section of to and the total hadronic cross section in annihilation in the bottomonium energy region are calcul…
Fast computation of observed cross section for decays
Wang Bo-Qun, Mo Xiao-Hu, Wang Ping +1
It has been conjectured that the relative phase between strong and electromagnetic amplitudes is universally in charmonium decays. decaying into pseudosc…
Baryon Antibaryon Nonets
C. Z. Yuan, X. H. Mo, P. Wang
The baryon-antibaryon SU(3) nonets are proposed as a scheme to classify the increased number of experimentally observed enhancements near the baryon antibaryon mass threshold. The…
Possible large branching fraction of psi(3770) decays to charmless final states
P. Wang, C. Z. Yuan, X. H. Mo
The branching fraction of the psi(3770) decays into charmless final states is estimated in the S- and D-wave charmonia mixing scheme. With the information of the hadronic decays of…
Measuring psi(3770) -> Kshort Klong as a test of the S- and D-wave mixing of charmonia
P. Wang, X. H. Mo, C. Z. Yuan
Adding to the long standing "rho-pi puzzle" in psi(3686) and J/psi decays, recently BES reported the branching ratio of psi(3686) -> Kshort Klong which is enhanced relative to the…
Relative phase between strong and electromagnetic amplitudes in psi(2S) to 0- 0- decays
C. Z. Yuan, P. Wang, X. H. Mo
With the known branching ratios of psi(2S) to pi+pi- and psi(2S) to K+K-, the branching ratio of psi(2S) to K0short K0long is calculated as a function of the relative phase between…
Possible large phase in psi(2S) -> 1-0- Decays
P. Wang, C. Z. Yuan, X. H. Mo
The strong and the electromagnetic amplitudes are analyzed on the basis of the measurements of J/psi, psi(2S) -> 1-0- in e+e- experiments. The currently available experimental info…
The Form Factors of omega pi0 and pi+ pi- at psi(2S)
P. Wang, X. H. Mo, C. Z. Yuan
The measurements of psi(2S) -> omega pi0 and psi(2S) -> pi+ pi- in e+e- experiments are examined. It is found that the non-resonance virtual photon annihilation gives large contrib…
