摘要：Hadron wave functions and form factors can be extracted using four-point correlators. Stochastic
techniques are used to estimate the all to all propagators, which are required for the exact
calculation of four-point functions. We apply the so called one-end trick to evaluate meson fourpoint
functions. We demonstrate the effectiveness of the technique in the case of the pion and the
r-meson where we extract their charge distribution, as well as the form factors.
