The radiative corrections of the electroweak chiral Lagrangian with renormalization group equations
Abstract
We show the computational procedure of the renormalization of the electroweak chiral Lagrangian (the 4D Higgsless standard model), and provide one simplified version of its one-loop renormalization group equations, which we demonstrate its simplicity and reliability. By analyzing the solutions of the one-loop renormalization group equations of the electroweak chiral Lagrangian, we study the parameter space of the precision test parameters at ultraviolet cutoff with the current low energy experimental constraints. We find that the region of the permitted parameter space can be greatly amplified (1 to 2 order) by the radiative corrections of those undetermined anomalous couplings.
