格畴壁费米子与交错费米子的交换子

Propagator of the lattice domain wall fermion and the staggered fermion

Sadataka Furui

摘要:

从RBC-UKQCD合作的规范位形和$16^3\times 32\times 16$格点的2+1动力学味计算了畴壁费米子的传播子。调整相位的模糊度,使得共轭梯度法的解与源处的平面波的重叠变为真实。质量函数变得接近Kogut-Susskind费米子的质量函数,但$u/d$ -夸克质量和s-夸克质量比接近0.75时没有出现反常行为.

英文摘要:

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.
