[email protected]. We use the on-shell S-matrix and form factors to compute anomalous dimensions of higher dimension operators in the Standard Model Effective Field Theory. Renormalization and the renormalization group (RG) were originally ... anomalous scaling properties found in quantum field theories, but here manifested in such problems as flow in porous media, the propagation ... Anomalous dimensions in partial differential equations. Lectures On Phase Transitions And The Renormalization Group. Polchinski's … All rights reserved. Anomalous dimensions and the multiplicative renormalization group. The purpose of this paper is to explain anomalous dimensions as a renormalization effect and to consider the scaling behavior of the renormalized theory in the framework of the renormalization group. Abstract. By Nigel Goldenfeld. Lectures On Phase Transitions And The Renormalization Group book. For free field theory in 3+1 dimensions for example, the expectation value of the Hamiltonian has a divergence of the form Fixed points and anomalous dimensions 172 5.1. Abstract. Anomalous dimensions and the renormalization group in a nonlinear diffusion process. A simple expression for the exactly marginal redundant operator proceeds from this … We present a renormalization-group (RG) approach to the nonlinear diffusion process ∂ t u=D ∂ 2 x u, with D=1/2 for ∂ 2 x u>0 and D=(1+∊)/2 for ∂ 2 x u<0, which describes the pressure during the filtration of an elastic fluid in an elastoplastic porous medium. ...

OSTI.GOV Journal Article: Anomalous dimensions and the multiplicative renormalization group. The latter arises due to the infinite number of degrees of freedom integrated over all space. Enter the renormalization group. The non-linear way the anomalous dimension parameter has been introduced in the historic first version of the exact renormalization group equation is compared to current practice. Irrelevant variables and thee expansion 111 13. We present a renormalization-group (RG) approach to the nonlinear diffusion process ∂ t u=D ∂ 2 x u, with D=1/2 for ∂ 2 x u>0 and D=(1+∊)/2 for ∂ 2 x u<0, which describes the pressure during the filtration of an elastic fluid in an elastoplastic porous medium.

(in russian) The non-linear way the anomalous dimension parameter has been introduced in the historic first version of the exact renormalization group equation is compared to current practice. In quantum physics an anomaly or quantum anomaly is the failure of a symmetry of a theory's classical action to be a symmetry of any regularization of the full quantum theory. 4 The Renormalization Group 4.1 The β-function The value of renormalized coupling constants are renormalization prescription dependent.

Functional Renormalization We study the renormalization group ow of the scalar models using functional renormalization group … Anomalous dimensions and the renormalization group equations Nuclear Physics B73 (1974) 339-350. Keywords: reaction–diffusion, renormalization group, anomalous dimension (Some figures may appear in colour only in the online journal) 1. In classical physics, a classical anomaly is the failure of a symmetry to be restored in the limit in which the symmetry-breaking parameter goes to zero.
