主 题:two-color QCD diquarks chiral perturbation theory axial isospin density NJL model
摘 要:We study the two-color QCD matter with two fundamental quark flavors using the chiral perturbation theory and the Nambu-Jona-Lasinio(NJL)*** effective Lagrangian is derived in terms of mesons and baryons,*** low lying excitations lie in the extended SU(4)flavor symmetry *** compute the leading order terms of the Lagrangian as a function of the baryon and axial isospin *** numerically solving the gap equations in the two-color NJL model,the phase diagram is obtained in the μ−ν5 plane.
