متن کاملSpectrum Results with Kogut-Susskind Quarks
The Kogut-Susskind formulation of lattice fermions, often called “staggered fermions”, has long been a popular formulation for QCD simulations including dynamical quarks. The basic reason for this is the single remaining exact chiral symmetry, which is sufficient to protect the quark mass from additive renormalization. From a practical viewpoint, an important consequence is a lower limit on the...
متن کاملTests of Improved Kogut-Susskind Fermion Actions
Improvements of the Kogut-Susskind quark action may allow extraction of continuum physics from coarser lattices than would be required with the simplest formulation. This is especially important for full QCD simulations, which are much more time consuming than quenched calculations. Improvement of the rotational symmetry and the dispersion relation can be achieved by introducing the Naik term, ...

Several topics concerning the light hadron spectrum are discussed. Flavor symmetry breaking effects and the problem of quenched chiral logarithm are examined with pion mass data for the Kogut-Susskind quark action, and light meson decay constants for the Wilson action calculated with non-perturbative renormalization constants are discussed. Results for quark masses are also given both for the K...
