The anomalous dimension of the composite operator A in the Landau gauge
نویسندگان
چکیده
The local composite operator A2 is analysed in pure Yang-Mills theory in the Landau gauge within the algebraic renormalization. It is proven that the anomalous dimension of A2 is not an independent parameter, being expressed as a linear combination of the gauge β function and of the anomalous dimension of the gauge fields.

The anomalous dimension of the gluon-ghost mass operator in Yang-Mills theory
The local composite gluon-ghost operator ( 1 2 AA μ + αcc ) is analysed in the framework of the algebraic renormalization in SU(N) Yang-Mills theories in the Landau, CurciFerrari and maximal abelian gauges. We show, to all orders of perturbation theory, that this operator is multiplicatively renormalizable. Furthermore, its anomalous dimension is not an independent parameter of the theory, bein...
متن کاملGluon - ghost condensate of mass dimension 2 in the Curci - Ferrari gauge
The effective potential for an on-shell BRST invariant gluon-ghost condensate of mass dimension 2 in the Curci-Ferrari gauge in SU(N) Yang-Mills is analysed by combining the local composite operator technique with the algebraic renormalization. We pay attention to the gauge parameter independence of the vacuum energy obtained in the considered framework and discuss the Landau gauge as an intere...
متن کاملInfrared features of unquenched Lattice Landau Gauge QCD
The running coupling and the Kugo-Ojima parameter of unquenched lattice Landau gauge are simulated and compared with the continuum theory. Although the running coupling measured by the ghost and gluon dressing function is infrared suppressed, the running coupling has the maximum of α0 ∼ 2−2.5 at around q = 0.5GeV irrespective of the fermion actions (Wilson fermions and Kogut-Susskind(KS) fermio...
متن کاملFour-loop renormalization of QCD: full set of renormalization constants and anomalous dimensions
The anomalous dimensions of the gluon and ghost fields as well as those of the ghost-ghost-gluon and quark-quark-gluon vertexes are analytically computed at four loops in pQCD. Taken together with already available anomalous dimensions of the coupling constant, the quark field and the mass the results lead to complete knowledge of all renormalization constant entering into the renormalization o...
متن کاملAnomalous dimension of the gluon operator in pure Yang-Mills theory.
We present new one loop calculations that confirm the theorems of Joglekar and Lee on the renormalization of composite operators. We do this by considering physical matrix elements with the operators inserted at non-zero momentum. The resulting IR singularities are regulated dimensionally. We show that the physical matrix element of the BRST exact gauge variant operator which appears in the ene...
