Algebraic algorithm for the computation of one-loop Feynman diagrams in lattice QCD with Wilson fermions
We describe an algebraic algorithm which allows to express every one-loop lattice integral with gluon or Wilson-fermion propagators in terms of a small number of basic constants which can be computed with arbitrary high precision. Although the presentation is restricted to four dimensions the technique can be generalized to every space dimension. Various examples are given, including the one-lo...
متن کاملHow to compute one-loop Feynman diagrams in lattice QCD with Wilson fermions
We describe an algebraic algorithm which allows to express every one-loop lattice integral with gluon or Wilsonfermion propagators in terms of a small number of basic constants which can be computed with arbitrary high precision. Although the presentation is restricted to four dimensions the technique can be generalized to every space dimension. We also give a method to express the lattice free...
متن کاملThree-Loop Results in QCD with Wilson Fermions
We calculate the third coefficient of the lattice beta function in QCD with Wilson fermions, extending the pure gauge results of Lüscher and Weisz; we show how this coefficient modifies the scaling function on the lattice. We also calculate the three-loop average plaquette in the presence of Wilson fermions. This allows us to compute the lattice scaling function both in the standard and energy ...

متن کاملHamiltonian Lattice QCD with Wilson Fermions at Strong Coupling
Hamiltonian lattice QCD with Wilson fermions is investigated systematically by strongcoupling expansion up to the second order. The effective Hamiltonian is diagonalized by Bogoliubov transformation. The vacuum energy, chiral condensate, pseudo-scalar and vector meson masses are calculated. The comparison with the unitary transformation method by Luo and Chen is also made. The method discussed ...
