Abstract

The reaction pp → p f p s ( K + K − K + K − ) in which the K + K − K + K − system is centrally produced has been studied at 450 GeV/c. φφ production has been found to dominate this reaction and is compatible with being produced by double Pomeron exchange. An angular analysis of the φφ system favours J PC =2 ++ and its dP T dependence is similar to that observed for glueball candidates.
