Description

2012 saw unprecedented levels of pile-up (multiple interactions per bunch crossing) in collisions at the LHC. This presented a challenging environment in which to calibrate jets for use in both precision analyses and new physics searches. This poster details the jet-area-based pile-up suppression techniques that were developed by ATLAS for 2012 data taking and form the first stage in the jet energy calibration scheme.
