• The same, well known, det Σ+ det Σ term in effective theories, which 't Hooft showed is generated by instantons in QCD and which resolves the U_A(1) problem giving mass, in particular to the η' is for three light flavors shown to give three classical minima along the U_A(1) circle. The three minima are related to the center Z(3) of SU(3). The term also contributes, in a similar way as the diquark model of Jaffe, to an inverted scalar mass spectrum for the light scalars. The three vacua suggests a connection to the strong CP problem and confinement.
