Studying squark mass spectrum through gluino decay at 100 TeV future hadron colliders

TL;DR

This paper explores how future 100 TeV colliders can analyze gluino decays in supersymmetry to infer squark mass spectra, even when squarks are too heavy to produce directly.

Contribution

It proposes a method using decay signatures like high $p_T$ leptons and jets to determine gaugino types and quark flavors, revealing squark mass information indirectly.

Findings

Potential to identify gaugino species and quark flavors in gluino decays.

Ability to infer squark mass spectrum indirectly.

Background suppression using long-lived charged Wino.

Abstract

We study the prospect of determining the decay properties of the gluino in the supersymmetric (SUSY) standard model at a 100 TeV future hadron collider. We consider the case where the neutral Wino is the lightest superparticle. In this case, the long-lived charged Wino can be used to eliminate standard model backgrounds, which enables us to study the details of superparticles. We show that, based on the analysis of the numbers of high $p_T$ leptons, boosted $W$-jets, and $b$-tagged jets, we may determine the gaugino species and the quark flavors in the gluino decay. With such determinations, we can obtain information about the mass spectrum of squarks even if squarks are out of the kinematical reach.
