Pentaquark Baryons in String Theory -talk at Pentaquark 04-

چکیده
Pentaquark baryons Θ and Ξ−− are studied in the dual gravity theory of QCD in which simple mass formulae of pentaquarks are derived in the Maldacena prototype model for supersymmetric QCD and a more realistic model for ordinary QCD. In this approach it is possible to explain the extremely narrow decay widths of pentaquarks. With the aim of constructing more reliable mass formulae, a sketch is given on spin and the hyperfine interaction in the string picture.

Pentaquark 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...
متن کاملA Review of Pentaquark Calculations on the Lattice
The recent interest in pentaquark baryons has been inspired by the experimental discovery of Θ(1540) whose quark composition is uudds̄. We will not address the experimental situation. It is summarized by T. Nakano in his plenary talk during this conference 1. In the past few years, there has been quite an effort to calculate these pentaquark states to see if they can be observed in lattice QCD c...

The exotic baryon Θ + (1540 MeV) is visualised 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.
متن کاملHave Pentaquark States Been Seen?
The status of the search for pentaquark baryon states is reviewed in light of new results from the first two dedicated experiments from CLAS at Jefferson Lab and of new analyses from several labs on the Θ + (1540). Evidence for and against the heavier pentaquark states, the Ξ(1862) and the Θ 0 c (3100) observed at CERN and at HERA, respectively, are also discussed. I conclude that the evidence ...
