A mass preconditioning for lattice Dirac operators

Abstract

In a recent publication [ 1 ] we have proposed a preconditioning of the Dirac operator based on the factorisation of a predefined function related to the decay of the propagator with the distance. In this talk we discuss this numerical technique by arguing that it can be profitably used in order to improve the accuracy of correlators involving heavy quarks at large distances and eventually to accelerate the computation of light quark propagators
