Study of the e+e– 
0
process in the energy range 0.60 – 1.06 GeV
The process e+e– 0 in the energy range = 0.60 – 1.06 GeV was studied at VEPP-2M collider with SND detector using ~ 14 pb–1 of integrated luminosity. Data were analyzed in the framewor...

Vector Meson Property in Covariant Classification Scheme
Recently our collaboration group has proposed the covariant classification shceme of hadrons, leading to possible existence of two ground state vector mesons. One is corresponding to ordinary nonet a...

We present preliminary results of the analysis of the centrally produced system at 800 GeV/c in the reaction pp pslow()pfast. A partial wave analysis of the data up to 2.6 GeV/c2 shows that three waves with JPCLS = 2++02 and with different Jz and reflectivity are needed to describe the data. A fit to the wave amplitudes using Jost functions gives two resonances, one above and one below the threshold. The resonance above threshold has a Breit-Wigner structure with MR = 2.243 ± 0.015(stat) ± 0.010(syst) GeV and
