Commissioning of CMS and early standard model measurements with jets, missing transverse energy and photons at the LHC

TL;DR

This paper discusses the commissioning process of CMS, early standard model measurements involving jets, missing transverse energy, and photons, and strategies for optimizing their reconstruction with initial LHC collision data.

Contribution

It presents the CMS commissioning status, cosmic-ray muon results, and new strategies for early data analysis of key physics objects at the LHC.

Findings

CMS commissioning progress and cosmic-ray muon results

Strategies for optimizing jet, missing energy, and photon reconstruction

Preparedness for early standard model measurements at the LHC

Abstract

We report on the status and history of the CMS commissioning, together with selected results from cosmic-ray muon data. The second part focuses on strategies for optimizing the reconstruction of jets, missing transverse energy and photons for early standard model measurements at ATLAS and CMS with the first collision data from the Large Hadron Collider at CERN.
