Abstract
A new method for computing critical exponents based on renormalised Quantum Field Theory is presented. It arises from a new regularization procedure based on Stochastic Quantization. A version of this procedure, containing a dimensionless parameter ρ, allows an expansion analogous to the ε-expansion. Results to leading order are presented, showing at least the same accuracy as other methods to this order.
