Abstract
The present paper is a continuation of our previous work on the stochastic quantization of the -quantum field model on the two-dimensional torus. Making use of key properties of Gaussian multiplicative chaos and refining the method for singular SPDEs introduced in the previous work, we construct a unique time-global solution to the corresponding parabolic stochastic quantization equation in the full "-regime" of the charge parameter . We also identify the solution with an infinite-dimensional diffusion process constructed by the Dirichlet form approach.
