Publication Abstract: | We report on a sub-percent scale determination using the omega baryon mass and gradient-flow methods. The calculations are performed on 21 ensembles of Nf = 2 + 1 + 1 highly improved, rooted staggered sea-quark configurations generated by the MILC and CalLat Collaborations. The valence quark action used is Mo?bius Domain-Wall fermions solved on these configurations after a gradient- flow smearing is applied with a flowtime of tgf = 1 in lattice units. The ensembles span four lattice spacings in the range 0.06 . a . 0.15 fm, six pion masses in the range 130 . m? . 400 MeV and multiple lattice volumes. On each ensemble, the gradient-flow scale w0 /a and the omega baryon mass am? are computed. The dimensionless product of these quantities is then extrapolated to the continuum and infinite volume limits and interpolated to the physical light, strange and charm quark mass point in the isospin limit, resulting in the determination of w0 = 0.1706(12) fm with all sources of statistical and systematic uncertainty accounted for. The dominant uncertainty in this result, which is consistent with all other recent determinations, is the stochastic uncertainty, providing a clear path for a few-per-mille uncertainty as recently obtained by the BMWc Collaboration. |
