Meson form factors using four point functions
Presenter: Giannis Koutsou — University of Cyprus
C. Alexandrou and G. Koutsou
We evaluate hadronic form factors using four point correlators. Stochastic techniques are used to estimate the all to all propagator which in turn allows for the exact calculation of four point functions at any sink momentum. We demonstrate the applicability of our method by showing results for the pion and the ρ form factors. These are compared to recent results obtained within the standard three point function evaluation.
