The effects of explicit chiral symmetry breaking for domain wall fermions resulting from the finite size of the fifth dimension are discussed. The relation between the eigenfunctions of the five-dimensional transfer matrix and the residual mass are be reviewed and their effect on the operator mixing appearing in the calculation of B K is estimated. c Copyright owned by the author(s) under the t...

A system is frequently represented by transfer functions in an inputoutput characterization. However, such a system (under mild assumptions) can also be represented by transfer functions in a port characterization, frequently referred to as a chain-scattering representation. Due to its cascade properties, the chain-scattering representation is used throughout many fields of engineering. This pa...
