Single and Double Peripheral Production of Sigmas in Proton Proton Collisions

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 pp$\pi^0\pi^0$ and double sigma production in the pp$\pi^0\pi^0\pi^0\pi^0$ channels.
