Experimental investigations of strong interactions in non-perturbative QCD region

We have experimentally investigated the reactions π -p → φφn (OZI forbidden), φK+K-n (OZI allowed), K-p →φφ{σλ} (OZI allowed),φK+K-{σλ}(OZI allowed),bar pp → φ φ π 0 (OZI forbidden), φK+K-π0 (OZI allowed). By comparing the OZI forbidden (glueball filter) reactions with the OZI allowed and taking a global view we hope to critically test our hypothesis that the gT (2010), gT' (2300), and gT double-prime(2340) all with IGJPC = 0+2++ are produced by 1--3 2++ glueballs. We have searched for a Quark-Gluon Plasma by using 14.6 GeV/c x A Si ions incident on Au, Cu and Si. The novel detector used was a large solid angle TPC system. Although we found considerable strangeness enhancement this is explainable by conventional cascade physics including N* production. We have been engaged in phenomenological analyses in both glueball and heavy ion work. We have found that the θ(1720) is the same as the 0++ f0(1720) we discovered earlier. Furthermore that the G(1590) can be explained as a sum of the f0(1400) and f0(1720) and does not require a new resonant state. We have also found that the strangeness enhancement discovered in heavy ion collisions so far is explainable by conventional physics. We are in the STAR Collaboration at RHIC which uses a large TPC system to search for a Quark-Gluon Plasma
