Determining the Mass of Supersymmetric Scalars at the CLIC Multi-TeV e+e- Collider

TL;DR

This paper investigates methods to precisely measure the masses of supersymmetric scalar particles, such as smuons and scalar tops, at the future CLIC multi-TeV e+e- collider, considering various experimental effects.

Contribution

It compares the energy spectrum and threshold scan methods for mass determination and applies these techniques to different supersymmetric scenarios at CLIC.

Findings

Energy spectrum method effectively measures smuon mass.

Threshold scan provides accurate scalar top mass estimates.

Detector and background effects are significant factors in analysis.

Abstract

The determination of the smuon mass at the CLIC multi-TeV e+e- linear collider has been studied for two CMSSM benchmarks. Results are given for both the analysis of the muon energy spectrum and the threshold scan method. The effects of detector resolution, beam-beam interactions and accelerator- induced backgrounds are discussed. The energy spectrum technique is also applied to the \~t -> t ~g process to determine the scalar top mass, in scenarios with the gluino lighter than the squarks.
