Single-diffractive Drell-Yan pair production at the LHC

Understand

We present predictions for single-diffractive low-mass Drell-Yan pair production in $pp$ collisions at the LHC at $\sqrt{s}=13$ TeV.

• Predictions are obtained adopting a factorised form for the relevant cross sections and are based on a new set of diffractive parton distributions resulting from the QCD analysis of combined HERA leading proton data.
• We discuss a number of observables useful to characterise the expected factorisation breaking effects.
