abstract = {In a previous Letter [Borsanyi et al., Phys. Rev. Lett.
111, 252001 (2013)] we determined the isospin mass
splittings of the baryon octet from a lattice calculation
based on Nf=2+1 QCD simulations to which QED effects have
been added in a partially quenched setup. Using the same
data we determine here the corrections to Dashen’s theorem
and the individual up and down quark masses. Our ensembles
include 5 lattice spacings down to 0.054 fm, lattice sizes
up to 6 fm, and average up-down quark masses all the way
down to their physical value. For the parameter which
quantifies violations to Dashen’s theorem, we obtain
ϵ=0.73(2)(5)(17), where the first error is statistical, the
second is systematic, and the third is an estimate of the
QED quenching error. For the light quark masses we obtain,
mu=2.27(6)(5)(4) and md=4.67(6)(5)(4) MeV in the
modified minimal subtraction scheme at 2 GeV and the
isospin breaking ratios mu/md=0.485(11)(8)(14),
R=38.2(1.1)(0.8)(1.4), and Q=23.4(0.4)(0.3)(0.4). Our
results exclude the mu=0 solution to the strong CP problem
by more than 24 standard deviations.},
