Theoretical issues with staggered fermion simulations
arXiv:hep-lat/0509026
Abstract
The legality of the "rooting trick" in dynamical staggered fermion simulations is discussed, i.e. whether the theory with the Boltzmann weight $\det^{1/4}(D_\mathrm{st})$ yields the right continuum limit. Since the problem is unsolved, pieces of evidence in favor and against are collected and examined.
