Query: Determination of the renormalized heavy-quark mass in Lattice QCD   We study on the lattice the correlator of heavy-quark currents in the
vicinity of vanishing momentum. The renormalized charmed quark mass, the
renormalized strong coupling constant and gluon condensate can be defined in
terms of the derivatives of that correlator at zero momentum. We analyze
quenched Monte-Carlo data on a small lattice $8^3*16$ for $\beta=6$. We
generalize dispersion relations to the lattice theory in a simple way and use
them successfully to fit the correlator at both small and large distances. We
fit the short-distance part of the correlator with the relevant expressions of
perturbative QCD on the lattice and obtain the value of the renormalized quark
mass $m_c^{\bar{MS}}(m_c)\,=\,1.20(4)\,GeV$.
