Hadronic Coupling Constants in Lattice QCD
R. L. Altmeyer, M. Gockeler, R. Horsley +3
We calculate the hadronic coupling constants and in QCD, including dynamical quarks in the framework of staggered fermions in the lattice approach. For the nucl…
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…
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…
The Spin Content of the Nucleon
R. Altmeyer, M. Göckeler, R. Horsley +2
The fraction of the nucleon spin that is carried by the quarks, , is computed in lattice QCD with dynamical staggered fermions. We obtain the value .
Renormalisation of lattice currents and the calculation of decay constants for dynamical staggered fermions
R. Altmeyer, K. D. Born, M. Goeckeler +3
A numerical calculation of the lattice staggered renormalisation constants at , is presented. It is seen that there are considerable non-perturbative effects pr…
