Description

We study diffraction in proton-proton and ultra-peripheral heavy ion collisions at RHIC and the LHC using a gluon saturation-based model. The building blocks of the model are gluon ladders, singlet states of two-Reggeized gluons which satisfy the BFKL evolution equation, as well as multi-pomeron ($1\rightarrow 2, 2\rightarrow 3, 1\rightarrow 3$) vertices which describe how one pomeron may split into two or more. We use the Color Glass Condensate (CGC) formalism and JIMWLK evolution equation to derive explicit formulae for these vertices and show how this model can be used to study distribution of events with rapidity gaps in hard diffractive scattering in high energy proton-proton collisions.
