Functional Forms for Lattice Correlators at Small Times
arXiv:hep-lat/0111016 · doi:10.1016/S0920-5632(01)01690-5
Abstract
The analytic form of the lattice quark propagator is used to derive the functional form for short distance mesonic correlators. These are then used to calculate ``Continuum Model'' Ansatze which comprise of a pole, representing the ground state, plus a contribution for the excited states, coming from the short distance behaviour. These are compared to Monte Carlo data.
