Small eigenvalues of the SU(3) Dirac operator on the lattice and in Random Matrix Theory
M. Göckeler, H. Hehl, P. E. L. Rakow +2
We have calculated complete spectra of the staggered Dirac operator on the lattice in quenched SU(3) gauge theory for β= 5.4 and various lattice sizes. The microscopic spectral den…
Renormalization of four-fermion operators for higher twist calculations
S. Capitani, M. Göckeler, R. Horsley +4
The evaluation of the higher twist contributions to Deep Inelastic Scattering amplitudes involves a non trivial choice of operator bases for the higher orders of the OPE expansion…
Nucleon form factors and O(a) Improvement
S. Capitani, M. Gockeler, R. Horsley +9
Nucleon form factors have been extensively studied both experimentally and theoretically for many years. We report here on new results of a high statistics quenched lattice QCD cal…
Towards a Non-Perturbative Calculation of DIS Wilson Coefficients
S. Capitani, M. Göckeler, R. Horsley +4
We verify the operator product expansion (OPE) of deep inelastic scattering (DIS) on the lattice and present first results of a non-perturbative calculation of the Wilson coefficie…
Universal and non-universal behavior in Dirac spectra
M. E. Berbenni-Bitsch, M. Göckeler, S. Meyer +2
We have computed ensembles of complete spectra of the staggered Dirac operator using four-dimensional SU(2) gauge fields, both in the quenched approximation and with dynamical ferm…
Composite operators in lattice QCD: nonperturbative renormalization
M. Gockeler, R. Horsley, H. Oelrich +6
We investigate the nonperturbative renormalization of composite operators in lattice QCD restricting ourselves to operators that are bilinear in the quark fields. These include ope…
Crossover to Non-universal Microscopic Spectral Fluctuations in Lattice Gauge Theory
M. E. Berbenni-Bitsch, M. Göckeler, T. Guhr +7
The spectrum of the Dirac operator near zero virtuality obtained in lattice gauge simulations is known to be universally described by chiral random matrix theory. We address the qu…
Resolution of the Landau pole problem in QED
M. Göckeler, R. Horsley, V. Linke +3
We present new numerical results for the renormalized mass and coupling in non-compact lattice QED with staggered fermions. Implications for the continuum limit and the role of the…
