The Double Pomeron Exchange process is studied as a potential source for the production of gluonic bound states utilizing the intersecting Storage Rings at the European Organization for Nuclear Research in Geneva, Switzerland. Three different triggers are studied, which differ in the requirements placed on the slow central system produced by the Pomeron-Pomeron interaction. Exclusive four and six prong events are studied. A spin-parity analysis is performed on the ..pi../sup +/..pi../sup -/ system in the exclusive channel pp ..-->.. pp..pi../sup +/..pi../sup -/ for two of the triggers. The exclusive process pp ..-->.. ppK/sub S//sup 0/K /sup +/-/ ..pi../sup +/-/ is also studied and the K/sup 0/K..pi.. mass spectrum is examined. An enhancement is seen in the region of 1500 MeV, but it appears to originate from events which have missing tracks, rather than from the exclusive final state. While this does not preclude its interpretation as a genuine resonant state, it does not mean that a definite statement cannot be made on the basis of this analysis.
