Improvements to ATLAS track reconstruction for Run-2

Run-2 of the LHC will provide new challenges to track and vertex reconstruction with higher energies, denser jets and higher rates. In addition, the Insertable B-layer (IBL) is a fourth pixel layer, which has been inserted at the centre of ATLAS during the shutdown of the LHC. Improvements to track...

description Run-2 of the LHC will provide new challenges to track and vertex reconstruction with higher energies, denser jets and higher rates. In addition, the Insertable B-layer (IBL) is a fourth pixel layer, which has been inserted at the centre of ATLAS during the shutdown of the LHC. Improvements to track reconstruction developed during the two year shutdown of the LHC are discussed. These include novel techniques developed to improve the performance in the dense cores of jets, optimisation for the expected conditions, and a big software campaign which lead to a factor of four decrease in the CPU time needed to process each recorded event. The commissioning of the detector in preparation for Run-2 using cosmic data and collision data are presented.
