A nonperturbative effective model is derived for the Higgs sector of the Standard Model which is described by a simple scalar theory. The renormalized couplings are determined by the derivatives of the Gaussian effective potential that are known to be the sum of infinite bubble graphs contributing to the vertex functions. A good agreement has been found with strong coupling lattice simulations when a comparison can be made.

Gaussian Effective Potential

Quantum chaos in a quartic oscillator system given by [Formula: see text] is studied using Gaussian Effective Potential method. It is shown that though quantum fluctuations reduce chaos, there is a correspondence between classical behavior and quantum behavior with regard to integrability and chaos.
