Perturbative renormalization factors in domain-wall QCD with improved gauge actions
نویسندگان
چکیده
We evaluate renormalization factors of the domain-wall fermion system with various improved gauge actions at one loop level. The renormalization factors are calculated for quark wave function, quark mass, bilinear quark operators, threeand four-quark operators in MS scheme with the dimensional reduction(DRED) as well as the naive dimensional regularization(NDR). We also present detailed results in the mean field improved perturbation theory. 11.15Ha, 11.30Rd, 12.38Bx, 12.38Gc Typeset using REVTEX ∗on leave from Institute of Theoretical Physics, Kanazawa University, Ishikawa 920-1192, Japan

Non-perturbative renormalization of four-quark operators and BK with Schrödinger functional scheme in quenched domain-wall QCD
We present non-perturbative renormalization factors for ∆S = 2 four-quark operators in quenched domain-wall QCD using the Schrödinger functional method. Non-perturbative renormalization factor for BK is evaluated at hadronic scale. Combined with the non-perturbative RG running obtained by the Alpha collaboration, our result yields renormalization factor which converts lattice bare BK to the ren...
متن کاملPerturbative Renormalization Factors of Baryon Number Violating Operators for Improved Quark and Gauge Actions in Lattice QCD
We calculate one-loop renormalization factors of three-quark operators, which appear in the low energy effective Lagrangian of the nucleon decay, for O(a)-improved quark action and gauge action including six-link loops. This calculation is required to predict the hadronic nucleon decay matrix elements in the continuum regularization scheme using lattice QCD. We present detailed numerical result...
متن کاملPerturbative Renormalization Factors of Quark Bilinear Operators for Domain-wall QCD
We calculate one-loop renormalization factors of bilinear operators made of physical quark fields for domain-wall QCD. We find that finite parts of such renormalization factors have reasonable values at 1-loop except an overlap factor between the physical quark field and the zero mode in the theory. We point out that the 1-loop estimate of overall renormalization factors becomes unreliable at t...
متن کاملNon-perturbative renormalization of vector and axial vector currents in quenched QCD for a renormalization group improved gauge action
Renormalization constants of vector (ZV ) and axial-vector (ZA) currents are determined non-perturbatively in quenched QCD for an RG-improved gauge action and a tadpole-improved clover quark action using the Schrödinger functional method. Meson decay constants fρ and fπ show much better scaling when ZV and ZA estimated for infinite physical volume are used instead of Z-factors from tadpole-impr...
متن کاملResummation of Cactus Diagrams in the Clover Improved Lattice Formulation of QCD
We extend to the clover improved lattice formulation of QCD the resummation of cactus diagrams, i.e. a certain class of tadpole-like gauge invariant diagrams. Cactus resummation yields an improved perturbative expansion. We apply it to the lattice renormalization of some two-fermion operators improving their one-loop perturbative estimates.
