N2 - © 2015 Elsevier B.V. Using flavor-breaking chiral sum rules for the difference of flavor ud and us current-current two-point functions, with non-strange and strange hadronic τ decay data as input, we obtain accurate determinations of a number of SU(3) chiral NNLO low-energy constants. These results allow a significant improvement in the combined NNLO continuum-lattice determination of the NLO low-energy constant L10r, producing a current world best determination of L10r, and the first such NNLO determination having all NNLO effects under full control.
