Contribution

It introduces the FCM with an instantaneous formalism as a new approach to describe nonperturbative QCD phenomena without phenomenological parameters.

Findings

Connection of colorelectric confinement with quark and gluon condensates

Explicit form of colorelectric deconfinement at high T

Theory of colormagnetic confinement at all temperatures

Abstract

The recent development of the Field Correlator Method (FCM) is discussed, with applications to the most interesting areas of QCD physics obtained in the lattice data and experiment. These areas include: a) the connection of colorelectric confinement with the basic quark and gluon condensates; b) the explicit form of the colorelectric deconfinement at a growing temperature $T$; c) the theory of the colormagnetic confinement at all temperatures; d) the theory of strong decays, the theory of pdf and jets in the instantaneous formalism with confinement. We demonstrate that the FCM with instantaneous formalism and confinement (instead of the light cone formalism and pure perturbation theory) can provide the way to the theory of QCD, which helps to describe world data without phenomenological parameters.
