Proposal for a New Reconstruction Technique for SUSY Processes at the LHC

TL;DR

This paper introduces a new reconstruction method for supersymmetry processes at the LHC, enabling full kinematic reconstruction in decay channels with known sparticle masses, demonstrated through four specific examples.

Contribution

The paper presents a novel reconstruction technique for SUSY decay processes that allows full event kinematic reconstruction when sparticle masses are known.

Findings

Successful reconstruction of gluino and sbottom masses

Reconstruction of LSP momentum and heavy Higgs mass

Method applicable to leptonic decay channels

Abstract

When several sparticle masses are known, the kinematics of SUSY decay processes observed at the LHC can be solved if the cascade decays contain sufficient steps. We demonstrate four examples of this full reconstruction technique applied to channels involving leptons, namely a) gluino mass determination, b) sbottom mass determination, c) LSP momentum reconstruction, and d) heavy higgs mass determination.
