An Exact Rg Formulation of Quantum Gauge Theory
نویسنده
چکیده
A gauge invariant Wilsonian effective action is constructed for pure SU(N) YangMills theory by formulating the corresponding flow equation. Manifestly gauge invariant calculations can be performed i.e. without gauge fixing or ghosts. Regularisation is implemented in a novel way which realises a spontaneously broken SU(N |N) supergauge theory. As an example we sketch the computation of the one-loop β function, performed for the first time without any gauge fixing.

Manifestly Gauge Invariant Exact
We construct a manifestly gauge invariant Exact Renormalization Group for SU(N) Yang-Mills theory, in a form suitable for calculations without gauge fixing at any order of perturbation theory. The effective cutoff is incorporated via a manifestly realised spontaneously broken SU(N |N) gauge invariance. Diagrammatic methods are developed which allow the calculations to proceed without specifying...
متن کاملPerturbation theory and renormalisation group equations
Renormalisation group (RG) methods are an essential ingredient in the study of non-perturbative problems in continuum and lattice formulations of quantum field theory. A number of RG equations have been proposed, where the starting point is the (infrared) regularised one loop effective action. Taking the derivative w.r.t. the infrared scale together with a subsequent one loop improvement leads ...

متن کاملScreening Masses in SU(N) from Wilson Renormalization Group
We apply a gauge invariant formulation of Wilson Renormalization Group (RG) to the computation of the Debye and transverse gluon masses in pure gauge SU(N) at high temperature. Following the Hard Thermal Loop effective field theory as a guideline, we develop an approximation scheme to the exact evolution equations. The Debye mass receives sizable corrections compared to the leading order pertur...
متن کاملExact Renormalization Group for O(4) Gauged Supergravity
We study exact renormalization group (RG) in O(4) gauged supergrav-ity using the effective average action formalism. The nonperturbative RG equations for cosmological and newtonian coupling constants are found. It is shown the existence of (nonstable) fixed point of these equations. The solution of RG equation for newtonian coupling constant is qualitatively the same as in Einstein gravity (i.e...
