ATLAS Pixel IBL: Stave Quality Assurance
For Run 2 of the LHC a fourth innermost Pixel Detector layer on a smaller radius beam pipe has been installed in the ATLAS Detector to add redundancy against radiation damage of the current Pixel Detector and to ensure a high quality tracking and b-tagging performance of the Inner Detector over the coming years until the High Luminosity Upgrade.

Flavor Tagging with Track Jets in Boosted Topologies with the ATLAS Detector
The ability to resolve and b-tag heavy flavor jets produced from the decay of boosted heavy particles, such as top quarks or Higgs bosons, is vital for the identification of new physics signatures as the LHC moves to higher energies and luminosities in 2015. [...]
