Form factors of the meson from effective field theory and the lattice
Ulf-G. Meißner, Akaki Rusetsky, Ajay S. Sakthivasan +2
The calculation of resonance form factors in effective field theory as well as on the lattice is a highly challenging task. In a recent paper, we proposed a novel method based on t…
