Finite-volume effects for two-hadron states in moving frames
Finite-volume effects for two-hadron states in moving frames
We determine the finite-volume corrections to the spectrum and matrix elements of two-hadron states in a moving frame, i.e., one in which the total momentum of the two hadrons is non-zero. The analysis is performed entirely within field theory and the results are accurate up to exponential corrections in the volume. Our results for the spectrum are equivalent to those of Rummukainen and Gottlieb which had been obtained using a relativistic quantum mechanical approach. A technical step in our analysis is a simple derivation of the summation formulae relating the loop summations over the momenta of the two hadrons in finite volume to the corresponding integrals in infinite volume.

Abstract
We determine the finite-volume corrections to the spectrum and matrix elements of two-hadron states in a moving frame, i.e., one in which the total momentum of the two hadrons is non-zero. The analysis is performed entirely within field theory and the results are accurate up to exponential corrections in the volume. Our results for the spectrum are equivalent to those of Rummukainen and Gottlieb which had been obtained using a relativistic quantum mechanical approach. A technical step in our analysis is a simple derivation of the summation formulae relating the loop summations over the momenta of the two hadrons in finite volume to the corresponding integrals in infinite volume.
