The present status of non-compact lattice QED
M. Goeckeler, R. Horsley, P. E. L. Rakow +2
We give a 1993 update of non-compact lattice QED, in particular the chiral condensate, finite size effects and meson mass ratios. We compare descriptions of the phase transition. O…
Three-point functions in noncompact lattice QED
M. Goeckeler, R. Horsley, P. E. L. Rakow +1
We calculate fermion-antifermion-"meson" three-point functions in noncompact lattice QED with dynamical staggered fermions and use them to extract effective Yukawa couplings. The r…
The pi-N Sigma term - an evaluation using staggered fermions
R. Altmeyer, M. Goeckeler, R. Horsley +2
A lattice calculation of the pi-N sigma term is described using dynamical staggered fermions. Preliminary results give a sea term comparable in magnitude to the valence term.
The ``Spin'' Structure of the Nucleon - a lattice investigation
R. Altmeyer, M. Goeckeler, R. Horsley +2
We will discuss here an indirect lattice evaluation of the baryon axial singlet current matrix element. This quantity may be related to the fraction of nucleon spin carried by the…
