Chiral properties of the constituent quark model
We show that, in a model based exclusively on constituent-quark degrees of freedom interacting via a potential, the full axial current is conserved if the spectrum of Q̄Q states contains a massless pseudoscalar. The current conservation emerges nonperturbatively if the model satisfies certain constraints on (i) the axial coupling gA of the constituent quark and (ii) the Q̄Q potential at large dis...
متن کاملTetraquarks in a chiral constituent quark model
We analyze the possibility of heavy-light tetraquark bound states by means of a chiral constituent quark model. The study is done in a variational approach. Special attention is paid to the contribution given by the different terms of the interacting potential and also to the role played by the different color channels. We find a stable state for both qqc̄c̄ and qqb̄b̄ configurations. Possible deca...
متن کاملBaryons in Chiral Constituent Quark Model
Beyond the spontaneous chiral symmetry breaking scale light and strange baryons should be considered as systems of three constituent quarks with an effective confining interaction and a flavor-spin chiral interaction that is mediated by the octet of Goldstone bosons (pseudoscalar mesons) between the constituent quarks. One cannot exclude, however, the possibility that this flavor-spin interacti...
متن کاملBaryons in a Chiral Constituent Quark Model
In the low-energy regime light and strange baryons should be considered as systems of constituent quarks with confining interaction and a chiral interaction that is mediated by Goldstone bosons as well as by vector and scalar mesons. The flavorspin structure and sign of the short-range part of the spin-spin force reduces the SU(6)FS symmetry down to SU(3)F × SU(2)S , induces hyperfine splitting...
متن کاملImplications of η Coupling In The Chiral Constituent Quark Model
Using the latest data pertaining to ū− d̄ asymmetry and the spin polarization functions, detailed implications of the possible values of the coupling strength of the singlet Goldstone boson η′ have been investigated in the χCQM with configuration mixing. Using ∆u, ∆3, ū− d̄ and ū/d̄, the possible ranges of the coupling parameters a, α2a, β2a and ζ2a, representing respectively the probabilities of ...
