Joint Resummation for Gaugino Pair Production at Hadron Colliders

TL;DR

This paper presents a next-to-leading order calculation for gaugino pair production at hadron colliders, incorporating simultaneous resummation of large logarithms to improve prediction accuracy for spectra and cross sections.

Contribution

It introduces a combined resummation approach at NLL accuracy for both small transverse momentum and threshold regions in gaugino pair production.

Findings

Predictions align well with previous results but offer increased precision.

Resummation improves the reliability of cross section and spectrum calculations.

The method enhances theoretical understanding of gaugino production at colliders.

Abstract

We calculate direct gaugino pair production at hadron colliders at next-to-leading order of perturbative QCD, resumming simultaneously large logarithms in the small transverse-momentum and threshold regions to next-to-leading logarithmic accuracy. Numerical predictions are presented for transverse momentum and invariant mass spectra as well as for total cross sections and compared to results obtained at fixed order and with pure transverse-momentum and threshold resummation. We find that our new results are in general in good agreement with the previous ones, but often even more precise.
