Abstract
The spectral projectors method is a way to obtain a theoretically well posed definition of the topological susceptibility on the lattice. Up to now this method has been defined and applied only to Wilson fermions. The goal of this work is to extend the method to staggered fermions, giving a definition for the staggered topological susceptibility and testing it in the pure SU (3) gauge theory. Besides, we also generalize the method to higher-order cumulants of the topological charge distribution.File in questo prodotto:
