Description
Exactly integrable (in the Luttinger’s sense) quark models of quantum field theory with infinite correlation length are considered. We calculate the form of energy distribution and find out such a form results in an instability of standard vacuum quark ensemble---Dirac sea. Then the corresponding momentum distribution becomes infinitely narrow with momentum cutoff going to infinity and leads to large (unlimited) fluctuations. The comparative analysis of various vacuum ensembles - the Dirac sea, neutral ensemble and the BCS superconductor state is made. We make a clear choice in favor of the BCS state as the ground state of quark ensemble with color interaction.
