Chiral Soliton Model Vs Pentaquark Structure for Θ(1540)
نویسنده
چکیده
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 کاملPentaquark Θ∗ States in {27} Baryon Multiplet from Chiral Soliton Model
We estimate the mass and the width of pentaquark Θ∗ states in the {27} baryon multiplet from chiral soliton model. The calculations show that the mass of Θ∗ is about 1.60 GeV and the width for the process Θ∗ → KN is less than 44 MeV. We also discuss the search for the existence of Θ∗ states in physical processes.

متن کاملStructure and reactions of pentaquark baryons
We review the current status of the exotic pentaquark baryons. After a brief look at experiments of both positive and negative results, we discuss theoretical methods to study the structure and reactions for the pentaquarks. First we introduce the quark model and the chiral soliton model, where we discuss the relation of mass spectrum and parity with some emphasis on the role of chiral symmetry...
