Propagator of the lattice domain wall fermion and the staggered fermion

Understand

The propagator of the domain wall fermion is calculated from the gauge configurations of the RBC-UKQCD collaborations with 2+1 dynamical flavors of $16^3\times 32\times 16$ lattice.

• The ambiguity of the phase is adjusted such that the overlap of the solution of the conjugate gradient method and the plane wave at the source becomes real.
• The mass function becomes close to those of Kogut-Susskind fermion, but no anomalous behavior for $u/d$-quark mass and s-quark mass ratio close to 0.75 appears.
