【 摘 要 】

The performance of the different object reconstruction and identification algorithms in CMS has been studied on data collected in pp collisions at p s = 7 TeV and at p s = 8 TeV at the LHC. We present measurements of the reconstruction efficiencies, fake rates, and momentum scale and resolution, which are relevant for top physics analyses.
