Analysis on the diffractive production of W's and dijets at the DESY HERA and Fermilab Tevatron colliders

TL;DR

This paper analyzes diffractive W and dijet production at HERA and Fermilab Tevatron, comparing experimental data with theoretical models, and proposes a revised Ingelman-Schlein model to resolve discrepancies.

Contribution

It introduces a new version of the Ingelman-Schlein model to better align theoretical predictions with experimental diffractive production data.

Findings

Discrepancies between theory and experiment highlight conceptual challenges.

A revised model improves compatibility between predictions and measurements.

Analysis emphasizes the need for refined theoretical approaches in diffractive processes.

Abstract

Hadronic processes in which hard diffractive production takes place have been observed and analyzed in collider experiments for several years. The experimental rates of diffractive W's and dijets measured at the Tevatron and the cross sections of diffractively produced dijets recently obtained at the HERA experiment are the object of this analysis. We use the Pomeron structure function obtained from the HERA data by two different approaches to calculate the rates and cross sections for these processes. The comparison of theoretical predictions with the measured values reveals some discrepancies that make evident conceptual difficulties with such approaches. A new version of the Ingelman-Schlein model is proposed as an attempt to overcome such difficulties and make theory and data compatible.
