Four-loop renormalization of QCD with a reducible fermion representation of the gauge group: anomalous dimensions and renormalization constants
نویسندگان
چکیده
The renormalization constants of the gauge boson (gluon), ghost and fermion fields are analytically computed as well as those for the ghost-gluon vertex, the fermion-gluon vertex and the fermion mass. All other renormalization constants can be derived from these. Some of these results were already produced in Feynman gauge for the computation of the β-function of this model, which was recently published [1]. Here we present results for an arbitrary ξ-parameter.

Four-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 کاملExtended BRS Symmetry and Gauge Independence in On-Shell Renormalization Schemes
Extended BRS symmetry is used to prove gauge independence of the fermion renormalization constant Z2 in on-shell QED renormalization schemes. A necessary condition for gauge independence of Z2 in on-shell QCD renormalization schemes is formulated. Satisfying this necessary condition appears to be problematic at the three-loop level in QCD. In on-shell schemes, the fermion mass renormalization Z...
متن کاملThree-loop anomalous dimensions for squarks in supersymmetric QCD
In this paper we evaluate the renormalization constants and anomalous dimensions for the squark wave function and mass within supersymmetric QCD. These results complement the ones obtained in Ref. [1] and thus provide further confirmation on the applicability of dimensional reduction to supersymmetric QCD at three-loop order. The three-loop anomalous dimension constitute important input to prec...
متن کاملGauge Invariance and Anomalous Dimensions of a Light-Cone Wilson Loop in Light-Like Axial Gauge
Complete two-loop calculation of a dimensionally regularized Wilson loop with lightlike segments is performed in the light-like axial gauge with the Mandelstam-Leibbrandt prescription for the gluon propagator. We find an expression which exactly coincides with the one previously obtained for the same Wilson loop in covariant Feynman gauge. The renormalization of Wilson loop is performed in the ...
متن کاملA perturbative study of two four - quark operators in finite volume renormalization schemes LPHA
Starting from the QCD Schrödinger functional (SF), we define a family of renormalization schemes for two four-quark operators, which are, in the chiral limit, protected against mixing with other operators. With the appropriate flavour assignments these operators can be interpreted as part of either the ∆F = 1 or ∆F = 2 effective weak Hamiltonians. In view of lattice QCD with Wilson-type quarks,...
