Gauge-independent Thermal β Function in Yang-Mills Theory via the Pinch Technique
نویسنده
چکیده
It is proposed to use the pinch technique to obtain the gauge-independent thermal β function βT in a hot Yang-Mills gas. Calculations of βT are performed at one-loop level in four different gauges, (i) the background field method with an arbitrary gauge parameter, (ii) the Feynman gauge, (iii) the Coulomb gauge, and (iv) the temporal axial gauge. When the pinch contributions to the gluon self-energy are included, the same result is derived for βT in all four cases. PACS numbers: 11.10.Wx, 11.15.Bt, 12.38.Bx

متن کاملM ar 2 00 6 A Manifestly Gauge Invariant , Continuum Calculation of the SU ( N ) Yang - Mills two - loop β function
The manifestly gauge invariant exact renormalisation group provides a framework for performing continuum computations in SU (N) Yang-Mills theory, without fixing the gauge. We use this formalism to compute the two-loop β function in a manifestly gauge invariant way, and without specifying the details of the regularisation scheme.
متن کاملGeneralized Pinch Technique and the Background Field Method in General Gauges
It is shown that Cornwall’s pinch technique can be extended in a consistent diagrammatic way, so as to describe general background field gauges in Yang-Mills theories. The resulting one-loop Green’s functions are found to obey Ward identities identical to those derived from the classical action at the tree level. This generalization of the pinch technique may hence be related to the background ...
متن کاملThe pinch technique at two-loops: The case of mass-less Yang-Mills theories
The generalization of the pinch technique beyond one loop is presented. It is shown that the crucial physical principles of gauge-invariance, unitarity, and gauge-fixing-parameter independence are instrumental for accomplishing this task, and is explained how the aforementioned requirements single out at two loops exactly the same algorithm which has been used to define the pinch technique at o...
متن کاملExplicit Non-Abelian Monopoles in SU(N) Pure Yang-Mills Theory
It is well known that there are no static non-Abelian monopole solutions in pure Yang-Mills theory on Minkowski space R. We show that such solutions exist in SU(N) gauge theory on the spaces R2×S2 and R×S1×S2 with Minkowski signature (−+++). In the temporal gauge they are solutions of pure Yang-Mills theory on T × S, where T is R or S. Namely, imposing SO(3)-invariance and some reality conditio...
