Finite volume effects in weak hadronic decays
Finite volume effects in weak hadronic decays
In this talk we discuss finite-volume computations of two-body hadronic decays below the inelastic threshold (e.g. K -> decays). In particular we show how the relation between finite-volume matrix elements and physical amplitudes, recently derived by Lellouch and Luscher, can be extended to all elastic states under the inelastic threshold. We also provide a derivation of the Luscher quantization condition directly in quantum field theory.

Abstract
In this talk we discuss finite-volume computations of two-body hadronic decays below the inelastic threshold (e.g. K -> decays). In particular we show how the relation between finite-volume matrix elements and physical amplitudes, recently derived by Lellouch and Luscher, can be extended to all elastic states under the inelastic threshold. We also provide a derivation of the Luscher quantization condition directly in quantum field theory.
