Non-universal gaugino and scalar masses, hadronically quiet trileptons and the Large Hadron Collider

TL;DR

This paper explores a specific MSSM scenario with heavy gluinos and squarks but accessible lighter sparticles, highlighting hadronically quiet trileptons as promising signals for detection at the LHC.

Contribution

It identifies and analyzes a benchmark MSSM scenario with non-universal gaugino and scalar masses, emphasizing the significance of hadronically quiet trilepton signals for LHC searches.

Findings

Hadronically quiet trileptons are effective signals in this MSSM scenario.

Certain parameter regions yield significant trilepton signals.

Hadronically quiet trileptons outperform other signals in this context.

Abstract

We investigate the parameter space of the minimal supersymmetric Standard Model (MSSM) where the gluino and squark masses are much above 1 TeV but the remaining part of the sparticle spectrum is accessible to the Large Hadron Collider at CERN. After pointing out that such a scenario may constitute an important benchmark of gaugino/scalar non-universality, we find that hadronically quiet trileptons are rather useful signals for it. Regions of the parameter space, where the signal is likely to be appreciable, are identified through a detailed scan. The advantage of hadronically quiet trileptons over other types of signals is demonstrated.
