Bogolyubov-Hartree-Fock approach to studying the QCD ground state
arXiv:0811.4405 · doi:10.1103/PhysRevD.80.076001
Abstract
The quark's behaviour while influenced by a strong stochastic gluon field is analyzed. An approximate procedure for calculating the effective Hamiltonian is developed and the corresponding ground state within the Hartree-Fock-Bogolyubov approach is found. The comparative analysis of various Hamiltonian models is given and transition to the chiral limit in the Keldysh model is discussed in detail.
