Stochastic derivation of conformal anomaly

Journal Article · · Phys. Rev. D; (United States)

The conformal anomaly of the scalar and fermion fields in the background gravitational field is derived, in the framework of stochastic quantization, as a breaking of the naive Leibnitz formula. This breaking represents quantum effects. It is also shown that anomalous Ward-Takahashi identities are derived from a stationary property of physical observables.
