Phys. Rev. D 71, 094021 (2005) [6 pages]Single and double peripheral production of sigmas in proton-proton collisionsReceived 30 June 2004; revised 18 March 2005; published 27 May 2005 The Pomeron, which dominates high energy elastic and diffractive hadronic processes, must be largely gluonic in nature. We use a recent picture of a scalar glueball/sigma system with coupling of the sigma to glue determined from experiment to predict strong peripheral sigma production in the ppπ0π0 and double-sigma production in the ppπ0π0π0π0 channels. © 2005 The American Physical Society URL:
