| Title |
Improving flavor symmetry in the Kogut-Susskind hadron spectrum |
| Date |
1997-02 |
| Description |
We study the effect of modifying the coupling of Kogut-Susskind quarks to the gauge field by replacing the link matrix in the quark action by a ‘‘fat link,'' or sum of link plus three-link paths. Flavor symmetry breaking, determined by the mass difference between the Goldstone and non-Goldstone local pions, is reduced by approximately a factor of 2 by this modification. |
