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

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 \([1 \otimes \xi_5]\), which respect the same recursion relation as the \(\gamma_5\) operator in the continuum. Then we...
