Description

I report on a study of quenched QCD using staggered fermions being done with Rajan Gupta and Greg Kilcup. We calculate the I = 2 pion scattering length at β = 5.7 and 6, and find agreement with predictions from the chiral Lagrangian. I mention highlights of our spectrum calculation, including preliminary results at β = 6.4. 8 refs., 2 figs
