Strange quark stars within the Nambu–Jona-Lasinio model

We investigate the properties of charge-neutral {beta}-equilibrium cold quark matter within the Nambu--Jona-Lasinio model. The calculations are carried out for different ratios of coupling constants characterizing the vector and scalar 4-fermion interaction {xi}(equivalent to)G{sub V}/G{sub S}. It i...
