Description
The performance of the reconstruction, calibration and identification
electrons and photons with the ATLAS detector at the LHC is a key
component to realize the ATLAS full physics potential, both in the
searches for new physics and in precision measurements. For instance, they
all played a critical role in the discovery of a Higgs boson, announced by
the ATLAS Collaboration in 2012, and in the measurement of its properties.
We present a description of the algorithms used for the reconstruction and
identification of electron and photons with the ATLAS detector, as well as
results from the measurements of their efficiencies in pp collisions. The
electron and photon energy calibration procedure is discussed, as well as
its impact on the precise measurement of the Higgs boson mass.
