Diffractive production from the Color-Glass-Condensate

Abstract

The diffractive production at small-x, including diffractive photo-production of vector mesons and dijet are powerful probes of non-linear gluon-saturation dynamics. We show that the t-distribution of photo-production of different vector mesons and dijet exhibit some universal features which offer a unique opportunity to discriminate among saturation and non-saturation models. Therefore, diffractive photo-production at the LHC and future colliders provides useful information about the underlying dynamics of particle production in the saturation regime.

“…A good t resolution and high luminosity are required to perform an effective study. Similar conclusions were presented in the talk of A. Rezaeian [38], based on the impact-parameter dependent Color Glass Condensate (b-CGC) and Saturation (IP-Sat) dipole models.…”

“…Furthermore, J. Nystrand summarized exclusive and inclusive photonuclear interactions at RHIC and LHC, and comparison to MC simulations [36]. M. Ducati [37] and A. Rezaeian [38] presented the comparison of the predictions of their models to the central exclusive data.…”

“…A crude estimate of the saturation line 13 based on the DLA result in Eq. (21) yields [38] ρs(Y ) ≡ ln …”
