Electron and Photon Performance and Electron pt Spectrum Measurement with ATLAS in pp Collisions at sqrt{s} = 7 TeV

We discuss the early performance of the reconstruction of electrons and photons at ATLAS with a center-of-mass energy of 7 TeV. Using a data sample of about 15 nb^-1, we present a measurement of the transverse momentum distribution of inclusive electrons, as well as an observation of direct photons...

description We discuss the early performance of the reconstruction of electrons and photons at ATLAS with a center-of-mass energy of 7 TeV. Using a data sample of about 15 nb^-1, we present a measurement of the transverse momentum distribution of inclusive electrons, as well as an observation of direct photons and a measurement of the purity of this sample. We also demonstrate the reconstruction of J/psi mesons with a data sample of 78 nb^-1.
