Lepton studies with ATLAS and CMS early data

TL;DR

This paper discusses how early data from ATLAS and CMS will use leptons to calibrate detectors, understand systematics, and enable initial physics measurements at the LHC.

Contribution

It provides updated performance estimates and outlines the initial physics signals expected from leptons in early LHC data.

Findings

Expected first physics signals involving leptons

Calibration of detector performance using early data

Control of systematic uncertainties

Abstract

Leptons will play a key role in the first measurements performed by the LHC experiments. The ATLAS and CMS detectors are now built, and early estimates of their performances have been revisited. The expected first physics signals are described: they will shed light on the level of detector understanding and allow a control of the systematics uncertainties, opening the road to new and precision physics.
