Diffractive gauge bosons production beyond QCD factorization

Pasechnik, Roman LU ; Kopeliovich, B. Z. and Potashnikova, I. K. (2012) In Physical Review D (Particles, Fields, Gravitation and Cosmology) 86(11).
Abstract
We discuss single diffractive gauge boson d (gamma*, W+/-, Z) production in proton-proton collisions at different (Large Hadron Collider and Relativistic Heavy Ion Collider) energies within the color dipole approach. The calculations are performed for gauge bosons produced at forward rapidities. The diffractive cross section is predicted as a function of the fractional momentum and invariant mass of the lepton pair. We found a dramatic breakdown of the diffractive QCD factorization caused by an interplay of hard and soft interactions. Data from the CDF experiment on diffractive production of W and Z are well explained in a parameter-free way. DOI: 10.1103/PhysRevD.86.114039
