Description

The RBC and UKQCD Collaborations continue to generate 2+1 flavor
domain wall fermion ensembles to support a variety of physics goals.
With the current set of ensembles, which includes one with physical
quark masses and an inverse lattice spacing of 2.7 GeV, we can
revisit the scale setting approach we have previously used in Phys.
Rev. D 93 (2016) 7, 074505. This global-fit approach involves a
simultaneous fit to a number of observables on a collection of
ensembles, using an expansion in light-quark masses and finite
lattice spacing errors, along with an expansion about the physical
strange quark mass. We report on our results to date, along with
our estimates of the systematic errors in our procedure.
