Flavor Twisted Boundary Conditions, Pion Momentum, and the Pion Electromagnetic Form Factor
arXiv:hep-lat/0610103 · doi:10.1016/j.physletb.2006.12.041
Abstract
We investigate the utility of partially twisted boundary conditions in lattice calculations of meson observables. For dynamical simulations, we show that the pion dispersion relation is modified by volume effects. In the isospin limit, we demonstrate that the pion electromagnetic form factor can be computed on the lattice at continuous values of the momentum transfer. Furthermore, the finite volume effects are under theoretical control for extraction of the pion charge radius.
