QCD factorisation breaking in diffractive gauge bosons production at the LHC
Summary, in English
We discuss single diffractive gauge bosons (γ*, W±, Z) production in proton-proton collisions at LHC energy (14 TeV) in the framework of 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 fractional momentum and invariant mass of the lepton pair. We found a dramatic breakdown of the diffractive QCD factorisation caused by an interplay of hard and soft interactions.
