Renormalized Lattice Perturbation Theory

چکیده
Apparent large failures of perturbation theory in lattice gauge theory at g* 5 1.0 result from the use of the bare coupling constant of the lattice regulator in the perturbative expansion. They can be cured by the use of a coupling constant defined by some physical process. Thissituation is thesame as that encountered in dimensionally regularized perturbation theory, where the use of a coupling constant definition suggested by the regulator (the MS scheme) can make the perturbative expansion appear to be more poorly behaved then it really is.

Properties of the renormalized quark mass in the Schrödinger functional with a non–vanishing background field
We compute the current quark mass in the Schrödinger functional with a non–vanishing background field at one loop order of perturbation theory. The results are used to obtain the critical mass at which the renormalized quark mass vanishes, and some lattice artefacts at one loop order.
متن کاملImproving lattice perturbation theory.
Lepage and Mackenzie have shown that tadpole renormalization and systematic improvement of lattice perturbation theory can lead to much improved numerical results in lattice gauge theory. It is shown that lattice perturbation theory using the Cayley parametrization of unitary matrices gives a simple analytical approach to tadpole renormalization, and that the Cayley parametrization gives lattic...
متن کاملO ( a ) improved twisted mass lattice QCD
Lattice QCD with Wilson quarks and a chirally twisted mass term (tmQCD) has been introduced in refs. [1,2]. We here apply Symanzik’s improvement programme to this theory and list the counterterms which arise at first order in the lattice spacing a. Based on the generalised transfer matrix, we define the tmQCD Schrödinger functional and use it to derive renormalized on-shell correlation function...
متن کاملLattice Qcd with the Overlap-dirac Operator: Its Λ Parameter, and One-loop Renormalization of Fermionic Currents
We compute the ratio between the scale ΛL associated with a lattice formulation of QCD using the overlap-Dirac operator, and Λ MS . To this end, the one-loop relation between the lattice coupling g0 and the coupling renormalized in the MS scheme is calculated, using the lattice background field technique. We also compute the one-loop renormalization ZΓ of the two-quark operators ψ̄Γψ, where Γ de...
متن کاملThe renormalized gauge coupling and non-perturbative tests of dimensional reduction
In 4d lattice simulations of Standard Model like theories, the renormalized gauge coupling in the broken phase can be determined from the prefactor of the Yukawa term in the static potential. We compute the same quantity in terms of the conventional MS scheme gauge coupling. The result allows for a further non-perturbative test of finite temperature dimensional reduction, by a comparison of the...
