Gauge-invariant quark-antiquark nonlocal condensates in QCD: a new interpretation of the lattice results

Abstract: The asymptotic large-distance behaviour of the gauge-invariant quark-antiquark ($\bar{q} q$) nonlocal condensates in QCD is derived by making use of a relation of these correlators to the two-point functions for the scalar and pseudoscalar $\bar{Q} q$ mesons in the limit of the heavy-quark mass $m_Q$ going to infinity. A comparison of this analytical result with the available lattice data is performed.
