Part of the Springer Theses book series (Springer Theses)


This chapter describes the reconstruction of the main physics objects that are relevant for the analyses presented in this dissertation. The identification, reconstruction and calibration of electrons, muons, jets, b-jets and missing transverse energy is discussed in detail. A brief description of the systematic uncertainties associated with these physics objects is also included.
