I review the present state of our knowledge about the masses and weak mixing elements of the u, d, s quarks. This is the written version of lectures given in the 1993 Theoretical Advanced Study Instit...
QCD condensates for the light quark V-A correlator
Energy decay data electroweak penguin operators

We use the procedure of pinched-weight finite energy sum rules to determine the operator product expansion (OPE) coefficients a6,…,a16 of the flavor ud V-A correlator in terms of existing hadronic τ d...
Lattice QCD at the physical point: light quark masses
Lattice QCD physical point light quark masses

Ordinary matter is described by six fundamental parameters: three couplings (gravitational,
electromagnetic and strong) and three masses: the electron’s (me) and those of the up (mu)
and down (md) q...
