Quark Confinement in a Constituent Quark Model
On the level of an effective quark theory, we define confinement by the absence of quark anti-quark thresholds in correlation functions. We then propose a confining Nambu-Jona-Lasinio-type model. The confinement is implemented in analogy to Anderson localization in condensed matter systems. We study the model's phase structure as well as its behavior under extreme conditions, i.e. high temperat...
متن کاملThree-body Confinement Forces in a Realistic Constituent Quark Model
We implement a three-body confinement force, introduced on an algebraic basis, into a semirelativistic version of the Goldstone-boson-exchange constituent quark model. By solving the Faddeev equations we show that this interaction can increase the gap between singlet and colour states, such as the latter can be ignored. We present results for a ∆and a Y-shape threebody interaction in terms of t...

We implement a three-body confinement force, introduced on an algebraic basis, into a semirelativistic version of the Goldstone-boson-exchange constituent quark model. By solving the Faddeev equations we show that this interaction can increase the gap between singlet and colour states, such as the latter can be ignored and the known baryons can be described as q3 systems. We analyze the effect ...
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 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...
