Missing transverse energy significance at CMS

Abstract

Missing transverse energy significance may be used to help distinguish real missing transverse energy due to undetected particles from spurious missing transverse energy due to resolution smearing. We present a description of the missing transverse energy significance variable, and assess its performance in Z$\to \hat{I}¼\hat{I}¼$, dijet, and W$\to e\hat{I}½$ events using the CMS 8 TeV dataset.
