Renormalization of SU(2) Yang-Mills theory with Flow Equations
Alexander N. Efremov, Riccardo Guida, Christoph Kopper
We give a proof of perturbative renormalizability of SU(2) Yang--Mills theory in four-dimensional Euclidean space which is based on the Flow Equations of the renormalization group.…
All-order uniform momentum bounds for the massless phi^4 theory in four dimensional Euclidean space
Riccardo Guida, Christoph Kopper
A panoramic overview is given, of a theorem [1] establishing physical and uniform bounds on the Fourier-transformed Schwinger functions of a massless phi^4 theory in four Euclidean…
Towards a fully automated computation of RG-functions for the 3- O(N) vector model: Parametrizing amplitudes
Riccardo Guida, Paolo Ribeca
Within the framework of field-theoretical description of second-order phase transitions via the 3-dimensional O(N) vector model, accurate predictions for critical exponents can be…
A new class of short distance universal amplitude ratios
M. Caselle, P. Grinza, R. Guida +1
We propose a new class of universal amplitude ratios which involve the first terms of the short distance expansion of the correlators of a statistical model in the vicinity of a cr…
Exact Consequences of the Trace Anomaly in Four Dimensions
Andrea Cappelli, Riccardo Guida, Nicodemo Magnoli
The general form of the stress-tensor three-point function in four dimensions is obtained by solving the Ward identities for the diffeomorphism and Weyl symmetries. Several propert…
Critical Exponents of the N-vector model
Riccardo Guida, Jean Zinn-Justin
Recently the series for two RG functions (corresponding to the anomalous dimensions of the fields phi and phi^2) of the 3D phi^4 field theory have been extended to next order (seve…
