Query: The Quark-Gluon Mixed Condensate g<\bar{q} sigma G q> in SU(3)c Quenched
  Lattice QCD   Using the SU(3)c lattice QCD with the Kogut-Susskind fermion at the quenched
level, we study the quark-gluon mixed condensate g<\bar{q} sigma G q>, which is
another chiral order parameter. For each current quark mass of m_q=21, 36, 52
MeV, we generate 100 gauge configurations in the 16^4 lattice with \beta = 6.0,
and perform the measurement of the mixed condensate at 16 points in each gauge
configuration. Using the 1600 data for each m_q, we find the ratio between the
mixed condensate and the quark condensate, m_0^2 = g<\bar{q} sigma G q>/
<\bar{q}q> \simeq 2.5 GeV^2 at the lattice scale in the chiral limit. The large
value of the mixed condensate suggests its importance in the operator product
expansion in QCD.
