Performance of Jet, Missing Transverse Energy and Tau Reconstruction with ATLAS in pp Collisions at $\sqrt{s}$ = 7 TeV

Mostrar otras versiones (1)

Preliminary results of jet, missing transverse energy, and tau reconstruction and calibration with the ATLAS detector form proton-proton collisions at sqrt(s)=7 TeV are presented. Inputs to jet, tau, and missing $E_T$ reconstruction and calibration are studied and validated with data. The jet energy...

description Preliminary results of jet, missing transverse energy, and tau reconstruction and calibration with the ATLAS detector form proton-proton collisions at sqrt(s)=7 TeV are presented. Inputs to jet, tau, and missing $E_T$ reconstruction and calibration are studied and validated with data. The jet energy calibration is derived from simulated QCD dijet events and its uncertainty determined using a combination of Monte Carlo, data, and test-beam data measurements. The initial ATLAS jet energy scale is determined with an uncertainty smaller than 10% for jets with transverse momentum greater than 20 GeV.
