Equivalence Theorem as a Criterion for Probing the Electroweak Symmetry Breaking Mechanism

Abstract

Based upon our recent study on the Lorentz non-invariance ambiguity in the longitudinal weak-boson scatterings and the precise conditions for the validity of the Equivalence Theorem (ET), we further examine the intrinsic connection between the longitudinal weak-boson scatterings and probing the electroweak symmetry breaking (EWSB) mechanism. We reveal the profound physical content of the ET as being able to discriminate processes which are insensitive to probing the EWSB sector. With this physical content as a criterion, we analyze the sensitivities to various effective operators for probing the mechanism of the EWSB.
