Analytical Properties and Unitarization

  • Rafael Delgado López
Chapter
Part of the Springer Theses book series (Springer Theses)

Abstract

This chapter includes a detailed study of the mathematical properties of the S-matrix, encoded in dispersion relations. Several unitarization procedures (IAM, N/D, old K-matrix and improved K-matrix) are studied in detail. We also consider a weak coupling of 2-\(\gamma \) and \(t\bar{t}\) states with a strongly interacting EWSBS. This requires a modification of the considered unitarization procedures, which is also providen.
