Resonances in an external field: the 1+1 dimensional case

Article

Abstract

Using non-relativistic effective field theory in 1+1 dimensions, we generalize Lüscher’s approach for resonances in the presence of an external field. This generalized approach provides a framework to study the infinite-volume limit of the form factor of a resonance determined in lattice simulations.
