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…
