Single and double peripheral production of sigmas in proton-proton collisions

<p>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 ppπ<sup>0</sup>π<sup>0</sup> and double-sigma production in the ppπ<sup>0</sup>π<sup>0</sup>π<sup>0</sup>π<sup>0</sup> channels.</p>
