TL;DR

This paper explores the minimal supersymmetric model's signals at the LHC, focusing on gluino production and decay, and assesses the discovery potential for gluino masses below 2300 GeV at 14 TeV.

Contribution

It introduces the least supersymmetric model with specific mass spectra and analyzes its LHC signatures, highlighting the discovery prospects for gluino masses under 2300 GeV.

Findings

Gluino production dominates signals in the model.

Discovery at 14 TeV is possible for gluino masses below 2300 GeV.

Large integrated luminosities are required for detection.

Abstract

We study the implications at the LHC for the minimal (least) version of the supersymmetric standard model. In this model supersymmetry is broken by gravity and extra gauge interactions effects, providing a spectrum similar in several aspects to that in natural supersymmetric scenarios. Having the first two generations of sparticles partially decoupled means that any significant signal can only involve gauginos and the third family of sfermions. In practice, the signals are dominated by gluino production with subsequent decays into the stop sector. As we show, for gluino masses below 2300 GeV, a discovery at the LHC is possible at \sqrt{s}=14 TeV, but will require large integrated luminosities.
