Contribution

It provides the first measurements of large rapidity gap cross sections in charged current processes at high Q2 and compares these with theoretical predictions.

Findings

Agreement with DGLAP-based parton density models

First measurement of charged current diffractive cross sections at high Q2

Enhanced understanding of proton structure in diffraction

Abstract

Recent precision measurements of diffractive neutral current deep inelastic ep scattering are performed by the H1 and ZEUS Collaborations at the HERA collider in a wide range of photon virtuality Q2. The first measurements of the large rapidity gap cross sections in charged current processes at high Q2 are also presented. The results are compared with model predictions based on parton density functions obtained from a DGLAP QCD fit to the data.
