New techniques for reconstructing and calibrating hadronic objects with ATLAS

Experimental uncertainties related to hadronic object reconstruction can limit the precision of physics analyses at the LHC, and so improvements in performance have the potential to broadly increase the impact of results. Recent refinements to reconstruction and calibration procedures for ATLAS jets and missing transverse momentum result in reduced uncertainties, improved pileup stability and other performance gains. In this contribution, highlights of these developments are presented.
