  Searches for new physics at the LHC will increasingly depend on identifying
deviations from precision Standard Model (SM) predictions. At the higher energy
scales involved for the LHC Run 2, the heavy quarks play a more prominent role
than at the Tevatron. Recent theoretical developments improve our ability to
address multi-scale problems and properly incorporate heavy quark masses across
the full kinematic range. These developments are incorporated into the new
nCTEQ15 PDFs, and we review these developments with respect to sample Run 2
measurements, and identify areas where additional effort is required.
