Issue Date: | 2006 | Citation: | Physics Letters B. 634:1 (2006) 48-54 | Abstract: | It is shown that U(3)L×U(3)R eight-quark interactions stabilize the asymmetric ground state of the well-known model with four-quark Nambu-Jona-Lasinio and six-quark 't Hooft interactions. The result remains when the reduced SU(3) flavour symmetry is explicitly broken by the general current quark mass term with . | URI: | https://hdl.handle.net/10316/4414 | DOI: | 10.1016/j.physletb.2006.01.008 | Rights: | openAccess |
