Computation of the improvement coefficient csw to 1-loop with improved gluon actions
نویسندگان
چکیده
The coefficient csw appearing in the Sheikholeslami-Wohlert improved action is computed to one loop perturbation theory for improved gluon actions including six-link loops. The O(a) improvement coefficients for the dimension three isovector composite operators bilinear in the quark fields are also computed to one loop order of perturbation theory with degenerate non-vanishing quark masses. ∗On leave from Institute of Physics, University of Tsukuba, Tsukuba, Ibaraki-305, Japan

Perturbative determination of cSW with Symanzik improved gauge action and stout smearing
We determine the improvement factor cSW in one-loop lattice perturbation theory for the plaquette and Symanzik improved gauge actions. The fermionic action is O(a) clover improved with onetime stout smearing. cSW is derived from the one-loop correction to the quark-quark-gluon vertex in the off-shell regime. We give a first numerical value for the one-loop contribution to the non gauge-invarian...
متن کاملPerturbative determination of cSW for plaquette and Symanzik gauge action and stout link clover fermions
Using plaquette and Symanzik improved gauge action and stout link clover fermions we determine the improvement coefficient cSW in one-loop lattice perturbation theory from the off-shell quark-quark-gluon three-point function. In addition, we compute the coefficients needed for the most general form of quark field improvement and present the one-loop result for the critical hopping parameter κc....
متن کاملPerturbative Renormalization Factors of Bilinear Quark Operators for Improved Gluon and Quark Actions in Lattice QCD
We calculate one-loop renormalization factors of bilinear quark operators for gluon action including six-link loops and O(a)-improved quark action in the limit of massless quark. We find that finite parts of one-loop coefficients of renormalization factors diminish monotonically as either of the coefficients c1 or c2 + c3 of the six-link terms are decreased below zero. Detailed numerical result...
متن کاملOne-loop renormalization factors and mixing coeffecients of bilinear quark operators for improved gluon and quark actions
We calculate one-loop renormalization factors and mixing coefficients of bilinear quark operators for a class of gluon actions with six-link loops and O(a)-improved quark action. The calculation is carried out by evaluating on-shell Green’s functions of quarks and gluons in the standard perturbation theory. We find a general trend that finite parts of one-loop coefficients are reduced approxima...
متن کاملGluons, Quarks, and the Transition from Nonperturbative to Perturbative Qcd
Lattice-based investigations of two fundamental QCD quantities are described, namely the gluon and quark propagators in Landau gauge. We have studied the Landau gauge gluon propagator using a variety of lattices with spacings from a = 0.17 to 0.41 fm to explore finite volume and discretization effects. We also introduce the general method of “tree-level correction” to minimize the effect of lat...
