We review our recent global analysis for probing the electroweak symmetry breaking (EWSB) mechanism by the universal effective Lagrangian description. After summarizing and commenting upon the current bounds for the EWSB parameters, we focus on testing them at the forthcoming high energy colliders such as the CERN LHC and the future linear colliders. We develop a precise electroweak power counting method (a la Weinberg) and formulate the longitudinal-Goldstone boson equivalence as a necessary criterion for sensitively probing the EWSB sector. Armed with these, we systematically estimate and classify the contributions of all next-to-leading order (NLO) bosonic operators to various scattering processes at the high energy colliders. The experimental signatures at these colliders are also analyzed. Furthermore, the complementarity of different scattering processes via different colliders for a complete probe of all these NLO effective operators is demonstrated.
