Probing Electroweak Symmetry Breaking Mechanism at the LHC: A Guideline from Power Counting Analysis

Abstract

We formulate the equivalence theorem as a theoretical criterion for sensitively probing the electroweak symmetry breaking mechanism, and develop a precise power counting method for the chiral Lagrangian formulated electroweak theories. Armed with these, we perform a systematic analysis on the sensitivities of the scattering processes W±W±W±W±W^\pm W^\pm \rightarrow W^\pm W^\pm and qqˉW±Zq\bar{q}'\rightarrow W^\pm Z for testing all possible effective bosonic operators in the chiral Lagrangian formulated electroweak theories at the CERN Large Hadron Collider (LHC). The analysis shows that these two kinds of processes are "complementary" in probing the electroweak symmetry breaking sector.Comment: Extended version, 11-page-Latex-file and 3 separate PS-Figs.
