摘要：

强子波函数和形状因子可以用四点展开器来提取。随机技术被用来估计所有到所有的传播，这是需要精确计算的四点函数。我们应用所谓的单端技巧来计算介子四点函数。我们证明了该技术的有效性的情况下，π介子和$ρ$介子，我们提取他们的电荷分布，以及形状因子。

英文摘要：

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 four-point functions. We demonstrate the effectiveness of the technique in the case of the pion and the $ρ$-meson where we extract their charge distribution, as well as the form factors.
