Electromagnetic mass splittings of the low lying hadrons and quark masses from 2+1 flavor lattice QCD+QED

Blum, T., Doi, T., Hayakawa, M. et al.

Understand

Results are presented for the electromagnetic mass splittings of the low lying hadrons.

  • These are used to determine the non-degenerate light quark masses.
  • It is found that m_u=2.24(10)(34), m_d=4.65(15)(32), and $m_s=97.6(2.9)(5.5)$ MeV (MSbar scheme, 2 GeV scale).
  • The first error is statistical and the second systematic.
