Masses, decay constants and electromagnetic formfactors with twisted boundary conditions
Abstract
We discuss some of the effects of twisted boundary conditions in finite volume using continuum SU(3) Chiral Perturbation Theory. We point out how broken cubic symmetry affects the definitions of quantities such as formfactors. Using the π+ as an example, we give one loop results for the mass, decay constants and electromagnetic formfactor and illustrate how the relevant Ward identities are satisfied.
