Constituent quark models and pentaquark baryons
نویسنده
چکیده
We discuss certain general features of the pentaquark picture for the θ, its 10F partner, Ξ3/2, and possible heavy quark analogues. Models employing spin-dependent interactions based on either effective Goldstone boson exchange or effective color magnetic exchange are also used to shed light on possible corrections to the Jaffe-Wilczek and KarlinerLipkin scenarios. Some model-dependent features of the pentaquark picture (splitting patterns and relative decay couplings) are also discussed in the context of these models.

Are there quasistable strange baryons with anticharm or antibeauty?
In some models, exotic baryons with strangeness and anticharm or antibeauty should exist and even be stable against strong decay. We consider the stability of such possible exotic baryons, which in the constituent quark picture are called pentaquarks (each is composed of four quarks and an antiquark). Our model is based on diquark clustering and supersymmetry in hadrons, and assumes that the sp...
متن کاملModel vs Pentaquark Structure for Θ ( 1540 )
The exotic baryon Θ + (1540 MeV) is visualized as an expected (iso) rota-tional excitation in the Chiral Soliton Model. It is also argued as a Pentaquark baryon state in a constituent quark model with strong diquark correlations. I contrast the two points of view; observe the similarities and differences between the two pictures. Collective excitation, characteristic of Chiral Soliton Model poi...
متن کاملPentaquark baryons in SU(3) quark model
We study the SU(3) group structure of pentaquark baryons which are made of four quarks and one antiquark. The pentaquark baryons form 1, 8, 10, 10, 27, and 35 multiplets in SU(3) quark model. First, the flavor wave functions of all the pentaquark baryons are constructed in SU(3) quark model and then the flavor SU(3) symmetry relations for the interactions of the pentaquarks with three-quark bar...

متن کاملFlavor Structure of Pentaquark Baryons in Quark Model
The flavor SU(3) group structure of pentaquark baryons which form 1, 8, 10, 10, 27, and 35 multiplets is investigated in quark model. The flavor wave functions of all the pentaquark baryons are constructed in SU(3) quark model and their Yukawa interactions with meson octet are obtained in general and in the special case of the octet-antidecuplet ideal mixing with the OZI rule. The mass sum rule...
