Chiral symmetry and taste symmetry from the eigenvalue spectrum of staggered Dirac operators

Hwancheol Jeong, Chulwoo Jung, Seungyeob Jwa +8

We investigate general properties of the eigenvalue spectrum for improved staggered quarks. We introduce a new chirality operator $[{\gamma }_5\otimes 1]$ and a new shift operator $[1 \ot…
