Precision predictions for direct gaugino and slepton production at the LHC

TL;DR

This paper provides highly precise theoretical predictions for direct gaugino and slepton production at the LHC, evaluates the accuracy of parton shower simulations, and reinterprets experimental data with broader particle decomposition models.

Contribution

It introduces the most accurate predictions to date for electroweak superpartners and assesses their impact on experimental analyses.

Findings

Enhanced precision in theoretical predictions for gaugino and slepton production.

Quantitative evaluation of parton shower simulation accuracy.

Reanalysis of experimental results with generalized gaugino and slepton models.

Abstract

The search for electroweak superpartners has recently moved to the centre of interest at the LHC. We provide the currently most precise theoretical predictions for these particles, use them to assess the precision of parton shower simulations, and reanalyse public experimental results assuming more general decompositions of gauginos and sleptons.
