Strongly interacting electroweak symmetry breaking sector

Abstract

The electroweak symmetry breaking sector of the standard model is reviewed. At a low energy scale, model independent approaches to electroweak symmetry breaking sector are realized by using electroweak chiral Lagrangian. We discuss the parameterization for gauge boson interactions and the connection of the parameters describing the triple gauge boson vertices $WW_γ$ and WWZ is obtained. We also calculate the process $e^+e^-→W^+W^-$ in the standard model.
