QCD rescattering mechanism for diffractive deep inelastic scattering

Pasechnik, Roman LU ; Enberg, Rikard and Ingelman, Gunnar (2010) In Physical Review D (Particles, Fields, Gravitation and Cosmology) 82(5).
Abstract

We present a QCD-based model where rescattering between final state partons in deep inelastic scattering leads to events with large rapidity gaps and a leading proton. In the framework of this model the amplitude for multiple gluon exchanges is calculated in the eikonal approximation to all orders in perturbation theory. Both large and small invariant mass MX limits are considered. The model successfully describes the precise HERA data on the diffractive deep inelastic cross section in the whole available kinematical range and gives new insight into the density of gluons at very small momentum fractions in the proton. © 2010 The American Physical Society.
