摘要
We begin with a progress report on a simulation of two flavor QCD with Kogut-Susskind quarks using the simplest gauge and quark actions. We then discuss some empirical investigations of the hadron spectrum with Kogut-Susskind quarks with improved gauge and quark actions. While these tests are done in the quenched approximation, we expect that improvement of the quenched spectrum is a good indicator of what can be expected in full QCD calculations.
