Probing the Continuum Limit in Non-Compact QED: New Results on Large Lattices
M. Goeckeler, R. Horsley, V. Linke +3
We present new Monte Carlo results in non-compact lattice QED with staggered fermions down to m_0 = 0.005. This extends our previous investigations on the nature of the continuum l…
Towards a Lattice Calculation of the Nucleon Structure Functions
M. Goeckeler, R. Horsley, M. Ilgenfritz +4
We have initiated a programme to compute the lower moments of the unpolarised and polarised deep inelastic structure functions of the nucleon in the quenched approximation. We revi…
Fermion-Fermion Scattering in the Gross-Neveu Model - a Status Report
M. Gockeler, H. A. Kastrup, J. Viola +1
Encouraged by the successful applications of Lüscher's method to boson--boson scattering we discuss the possibility of extracting scattering phase shifts from finite--volume energi…
Scattering phases on finite lattices in the broken phase of the four-dimensional O(4)-ϕ^4 theory
M. Goeckeler, H. A. Kastrup, J. Westphalen +1
According to a proposal of Luescher it is possible to determine elastic scattering phases in infinite volume from the energy spectrum of two-particle states in a periodic box. We d…
Spectroscopy and Renormalisation Group Flow of a Lattice Nambu-Jona-Lasinio Model
A. Ali Khan, M. Goeckeler, R. Horsley +3
We investigate a lattice Nambu--Jona-Lasinio model both by the Monte Carlo method and Schwinger-Dyson equations. A comparison allows the discussion of finite size effects and the e…
Hadronic coupling constants in lattice QCD
R. Altmeyer, M. Goeckeler, R. Horsley +3
We report on calculations of the hadronic coupling constants and based on lattice QCD with four flavors of dynamical staggered fermions. By computing 2--point a…
