Experimental investigations of strong interactions in non-perturbative QCD region (open access)

Experimental investigations of strong interactions in non-perturbative QCD region

We have experimentally investigated the reactions {pi} {sup {minus}}p {yields} {phi}{phi}n (OZI forbidden), {phi}K{sup +}K{sup {minus}}n (OZI allowed), K{sup {minus}}p {yields}{phi}{phi}{l brace}{sub {sigma}}{sup {lambda}}{r brace} (OZI allowed),{phi}K{sup +}K{sup {minus}}{l brace}{sub {sigma}}{sup {lambda}}{r brace}(OZI allowed),{bar p}p {yields} {phi} {phi} {pi} {sup 0} (OZI forbidden), {phi}K{sup +}K{sup {minus}}{pi}{sup 0} (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 g{sub T} (2010), g{sub T{prime}} (2300), and g{sub T}{double prime}(2340) all with I{sup G}J{sup PC} = 0{sup +}2{sup ++} are produced by 1--3 2{sup ++} glueballs. We have searched for a Quark-Gluon Plasma by using 14.6 GeV/c {times} 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 {theta}(1720) is the same as the 0{sup ++} f{sub 0}(1720) we discovered earlier. Furthermore that the G(1590) can be explained as a sum of the f{sub 0}(1400) and f{sub 0}(1720) and does …
