NNLO QCD corrections to the resonant sneutrino/slepton production at Hadron Colliders

TL;DR

This paper calculates precise NNLO QCD corrections for resonant sneutrino and slepton production at hadron colliders, reducing theoretical uncertainties and enhancing prediction reliability within R-parity violating supersymmetry.

Contribution

It provides the first complete NNLO QCD correction calculations for resonant sneutrino and slepton production, including soft gluon effects at N^3LO, within R-parity violating SUSY models.

Findings

NNLO corrections significantly increase predicted cross sections.

Corrections reduce uncertainties from renormalisation and factorisation scales.

Results are applicable to any color-neutral scalar resonance production.

Abstract

We present a complete next to next to leading order QCD corrections to the resonant sneutrino and charged slepton production cross sections at hadronic colliders such as the Tevatron and the Large Hadron Collider within the context of $R$-parity violating supersymmetric model. We have demonstrated the role of these corrections in reducing uncertainties resulting from renormalisation and factorisation scales and thereby making our predictions reliable. We have incorporated soft gluon effects at $N^3LO$ level in order to study the stability of our results under perturbation. The NNLO corrections are found to be large and significant. The results obtained in this article are also applicable to resonance production of any color-neutral scalar.
