Chiral limit of light hadron mass in quenched staggered QCD
  We discuss chiral limit of light hadron mass from our quenched staggered calculations with a high lattice cutoff of (a^{-1})(\sim)3.7 GeV at (\beta)=6.5 and a large lattice volume of (48^3\times 64). We added six heavier quark mass values of (m_qa)=0.0075, 0.015, 0.02, 0.03, 0.04 and 0.05 to the previously existing 0.01, 0.005, 0.0025, and 0.00125. An interesting curvature is observed in the (m_\pi^2/m_q) to (m_q) plot near (m_qa)=0.01.
