Exclusive SUSY measurements and determination of SUSY parameters from LHC data

TL;DR

This paper discusses how to measure and determine supersymmetry parameters at the LHC, focusing on reconstructing sparticle masses and model parameters from early data, assuming SUSY discovery.

Contribution

It introduces a method for extracting SUSY particle masses and model parameters from LHC data using exclusive measurements and endpoint techniques.

Findings

Sparticle masses can be reconstructed from mass spectrum endpoints.

Model parameters can be derived with early LHC data.

Demonstrates the approach on an mSUGRA example point.

Abstract

A selection of exclusive SUSY measurements is presented which can be performed provided SUSY will be discovered at the LHC. Such measurements allow to determine the properties of supersymmetry and thus help to pin down the underlying theoretical model. It is described on an mSUGRA example point how sparticle masses can be reconstructed from endpoints in mass spectra using early LHC data. Finally it is shown how well mSUGRA model parameters can be derived from these measurements.
