Masses, decay constants and electromagnetic form-factors with twisted boundary conditions

Relefors, Johan LU and Bijnens, Johan LU (2015) In Proceedings of Science 29-June-2015.
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 form-factors. Using the π+ as an example, we give one loop results for the mass, decay constants and electromagnetic form-factor and illustrate how the relevant Ward identities are satisfied.
