Boosting Stop Searches with a 100 TeV Proton Collider

TL;DR

A 100 TeV proton collider could significantly extend the search for supersymmetric stops, especially in boosted top regimes, using a simple muon-in-jet tagging method, with potential to discover or exclude stops up to 8 TeV.

Contribution

Proposes a new, simple boosted top-tagging strategy using muons inside jets for future 100 TeV colliders, enhancing stop search capabilities.

Findings

Collider can discover stops up to 6.5 TeV with 3000 fb^-1

Exclusion limits can reach up to 8 TeV

Simple muon-in-jet tagger is effective for boosted tops

Abstract

A proton-proton collider with center of mass energy around 100 TeV is the energy frontier machine that is likely to succeed the LHC. One of the primary physics goals will be the continued exploration of weak scale naturalness. Here we focus on the pair-production of stops that decay to a top and a neutralino. Most of the heavy stop parameter space results in highly boosted tops, populating kinematic regimes inaccessible at the LHC. New strategies for boosted top-tagging are needed and a simple, detector-independent tagger can be constructed by requiring a muon inside a jet. Assuming 20% systematic uncertainties, this future collider can discover (exclude) stops with masses up to 6.5 (8) TeV with 3000 fb^-1 of integrated luminosity. Studying how the exclusion limits scale with luminosity motivates going beyond this benchmark in order to saturate the discovery potential of the machine.
