Double Stochastic Quantization:Non perturbative approach to Stochastic Quantization λϕ_{d}²ⁿ,n≥2,d≥4 model Eucledean Quantum Field Theory

In this paper, we show how the finite formulation of quantum field theory based on Langevin equations can be generalized to the case of nonrenormalizable theories. The 5th-time stochastic-quantization approach to field theory proposed by Parisi and Wu, is put in a path-integral form in [6]. The procedure of taking the limit τ→∞ is analyzed and based on new grounds through the introduction of the vacuum-vacuum generating functional. In this paper non perturbative aprouch related to Parisi and Wu stochastic-quantization of the λϕ_{d}²ⁿ,n≥2,d≥4 model quantum field theory is considered.
