The locality of the fourth root of staggered fermion determinant in the interacting case
arXiv:hep-lat/0509176
Abstract
The fourth root approximation in LQCD simulations with dynamical staggered fermions requires justification. We test its validity numerically in the interacting theory in a renormalization group framework.
