Abstract

A study of the reactions pp → p_fp_s(K⁺K^- π⁺π^-) and pp → p_fp_s(K⁺ K^- π⁺π^- π⁰) shows evidence for the K * (892) K̄ * (892) and φω channels respectively. The K * (892) K̄ * (892) mass spectrum shows a broad distribution with a maximum near threshold and an angular analysis shows that it is compatible with having J^p = 2⁺. The behaviour of the cross-section as a function of centre of mass energy, and the four momentum transfer dependence, are compatible with what would be expected if the K * (892) K̄ * (892) system was produced via double Pomeron exchange. The dPT behaviour of the φω channel is similar to what has been observed for all the undisputed qq states. In contrast, the qq̄ behaviour of the K * (892) K̄ * (892) final state is similar to what has been observed for the φφ final state and for previously observed glueball candidates.
