Description

Electron identification is a crucial input to many ATLAS physics analysis. The electron identification used in ATLAS for run 2 is based on a likelihood discrimination to separate isolated electron candidates from candidates originating from photon conversions, hadron misidentification
and heavy flavor decays. In addition, isolation variables are used as further handles to separate
signal and background. The measurement of the efficiencies of the electron identification and isolation
cuts are performed with the data using tag and probe techniques with large statistics sample of Z->ee
and J/psi->ee decays. These measurements performed with pp collisions data at sqrt(s)=13 TeV in 2016 (2015)
corresponding to an integrated luminosity of 33.9 (3.1)fb-1 of sqrt(s)=13 TeV pp are presented.
