New results from WA102 experiment

A study of central meson production as a function of the azimuthal angle phi between the two outgoing protons show that the phi distributions are different for the different JPC of the central system and that the observed distributions are consistent with the DPE mediated by two vector Pomerons. In addition, the distributions of the difference in transverse momentum (dPT) of exchange particles are significantly different for the undisputed qqbar states and the glueball candidates. The S-wave spectrum of the centrally produced KKbar, and ππ systems show evidence on f0(980), f0(1370), f0(1500) and fJ(1710) states production. The spin of fJ(1710) is unambiguously identified as J=0
