Description
I will discuss that diffractive production at small-x, including diffractive photo production of vector mesons and dijet can be a powerful probe of non-linear gluon-saturation dynamics [1,2]. In particular, I will focus on the diffractive dijet production at HERA and the LHC within the color-glass-condensate approach [2]. I will show that the t-distribution of photoproduction of dijet and vector mesons at large |t| offers a unique opportunity to discriminate among saturation and non-saturation models. I will also show that diffractive dijet correlations at small-x exhibit some non-trivial novel features which are different from the inclusive two-particle correlations, like inclusive dijet, dihadron [3], diphoton [4] and photon-hadron [5] productions. Therefore, diffractive dijet photo-production at the LHC and future colliders provides useful complementary information about the underlying dynamics of particle production in the saturation regime.
