• Correlation function of local quark currents is defined. The simplest, two-point correlation function is formed by two quark-antiquark current operators sandwiched between the QCD vacuum states. This is a function of the 4-momentum transfer between the currents. In the region of large spacelike momentum transfers, the correlation function represents a short-distance fluctuation of quark-antiquark fields. The propagation of quarks and antiquarks at short distances is asymptotically free, the…
