Stueckelberg Mechanism and Chiral Lagrangian for $Z'$ Boson

High Energy Physics - Phenomenology 2009-01-06 v1

Abstract

Traditional Stueckelberg Mechanism is shown equivalent to set up a gauged U(1) chiral Lagrangian and fix special gauge. With this mechanism, the original electro-weak chiral Lagrangian is inlarged by including an extra U(1) symmetry to represent physics for ZZ' boson. We build up complete list of electro-weak chiral Lagrangian up to order of p4p^4 including ZZ' and higgs bosons. The most general mixing among neutral gauge bosons is diagonalized completely and the connections among these operators to triple, quartic couplings involving ZZ' boson and to that in traditional electro-weak chiral Lagrangian are made.
