b-tagging in the environment of boosted objects

The ability to b-tag heavy flavour jets produced within the high energy jets of boosted heavy particles, such as top quarks or Higgs bosons, will become vital for the identification of new physics signatures as the LHC moves to higher energies and luminosities in its second run. An improvement of the b-tagging efficiencies in these dense environments can be achieved by using small radius trackjets and dedicated b-tagging algorithms.
