BRS symmetry from renormalization group flow
M. Bonini, M. D'Attanasio, G. Marchesini
By using the exact renormalization group formulation we prove perturbatively the Slavnov-Taylor (ST) identities in SU(2) Yang-Mills theory. This results from two properties: {\it l…
BRS symmetry for Yang-Mills theory with exact renormalization group
M. Bonini, M. D'Attanasio, G. Marchesini
In the exact renormalization group (RG) flow in the infrared cutoff one needs boundary conditions. In a previous paper on Yang-Mills theory we proposed to use the nine…
High energy scattering in QCD and cross singularities of Wilson loops
I. A. Korchemskaya, G. P. Korchemsky
We consider elastic quark-quark scattering at high energy and fixed transferred momentum. Performing factorization of soft gluon exchanges into Wilson line expectation value we fin…
Eigenvalues of the Weyl operator as observables of general relativity
Roberto De Pietri, Carlo Rovelli
We consider the eigenvalues of the three-dimensional Weyl operator defined in terms of the (Euclidean) Ashtekar variables, and we study their dependence on the gravitational field.…
Monopole Gauge Fields and Quantum Potentials Induced by the Geometry in Simple Dynamical Systems
Paolo Maraner
A realistic analysis shows that constraining a quantomechanical system produces the effective dynamics to be coupled with {\sl abelian/non-abelian gauge fields} and {\sl quantum po…
Four Loop Result in Lattice Gauge Theory by a Stochastic Method: Lattice Correction to the Condensate
F. Di Renzo, G. Marchesini, P. Marenzoni +1
We describe a stochastic technique which allows one to compute numerically the coefficients of the weak coupling perturbative expansion of any observable in Lattice Gauge Theory. T…
Standard and Generalized Newtonian Gravities as ``Gauge'' Theories of the Extended Galilei Group - II: Dynamical Three-Space Theories
R. De Pietri, L. Lusanna, M. Pauri
In a preceding paper we developed a reformulation of Newtonian gravitation as a {\it gauge} theory of the extended Galilei group. In the present one we derive two true generalizati…
Standard and Generalized Newtonian Gravities as ``Gauge'' Theories of the Extended Galilei Group - I: The Standard Theory
R. De Pietri, L. Lusanna, M. Pauri
Newton's standard theory of gravitation is reformulated as a {\it gauge} theory of the {\it extended} Galilei Group. The Action principle is obtained by matching the {\it gauge} te…
Axial anomalies in gauge theory by exact renormalization group method
M. Bonini, M. D'Attanasio, G. Marchesini
The global chiral symmetry of a gauge theory is studied in the framework of renormalization group (RG). The theory is defined by the RG flow equations in the infrared cutof…
