Single-diffractive dijet production at high energies within the $k_t$ -factorization approach

TL;DR

This paper introduces a novel calculation of single-diffractive dijet production cross sections at high energies using the $k_t$-factorization approach, incorporating unintegrated parton distributions from established PDFs.

Contribution

It is the first to compute the cross section in the $k_t$-factorization framework for this process, neglecting the transverse momentum of the pomeron and utilizing UPDFs from MMHT2014nlo and H1 PDFs.

Findings

Successfully describes existing Tevatron data.

Provides detailed predictions for LHC measurements.

Demonstrates the applicability of $k_t$-factorization in diffractive processes.

Abstract

We discuss single-diffractive production of dijets. The cross section is calculated for the first time in the $k_t$-factorization approach, neglecting transverse momentum of the pomeron. We use Kimber-Martin-Ryskin unintegrated parton (gluon, quark, antiquark) distributions (UPDF) both in the proton as well as in the pomeron or subleading reggeon. The UPDFs are calculated based on conventional MMHT2014nlo PDFs in the proton and H1 collaboration diffractive PDFs used previously in the analysis of diffractive structure function and dijets at HERA. We try to describe the existing data from Tevatron and make detailed predictions for possible LHC measurements.
