Mass spectrum of pentaquarks
نویسنده
چکیده
We discuss the properties of the pentaquark in a collective stringlike model with a nonplanar configuration of the four quarks and the antiquark. In an application to the mass spectrum of exotic Θ baryons, we find that the ground state pentaquark has angular momentum and parity J = 1/2− and a small magnetic moment of 0.382 μN . The decay width is suppressed by the spatial overlap with the decay products.

Spectrum of the Y=2 Pentaquarks
By assuming a mass formula for the spectrum of the Y = 2 pentaquarks, where the chromo-magnetic interaction plays a main role, and identifying the lightest state with the Θ + (1540), we predict a spectrum in good agreement with the few I = 0 and I = 1 candidates proposed in the past.
متن کاملMass spectrum of spin-1/2 pentaquarks with a cc̄ component and their anticipated discovery modes in b-baryon decays
The LHCb discovery of the two baryonic states P c (4380) and P + c (4450), having J P = 3/2− and J = 5/2, respectively, in the process pp → bb̄ → ΛbX, followed by the decay Λb → J/ψ p K−, has motivated a number of theoretical models. Interpreting them as compact {c̄ [cu] [ud];LP = 0, 1} objects, the mass spectroscopy of the J = 3/2− and J = 5/2 pentaquarks was worked out by us for the pentaquarks...
متن کاملThe Discovery and Properties of Pentaquarks
The pentaquarks are exotic baryons formed of four quarks and an antiquarks. Their existence has been discussed in the literature over the last 30 years or more, first in connection with kaon nucleon scattering data. The subject has been revived by the end of 2002 when experimental evidence of a narrow baryon of strangeness S = + 1, and mass M ≃ 1530 MeV has been found. This is interpreted as th...
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...
متن کاملPositive parity pentaquark towers in large N c QCD
We construct the complete set of positive parity pentaquarks, which correspond in the quark model to s̄qNc+1 states with one unit of orbital angular momentum L = 1. In the large Nc limit they fall into the K = 1/2 and K = 3/2 irreps (towers) of the contracted SU(4)c symmetry. We derive predictions for the mass spectrum and the axial couplings of these states at leading order in 1/Nc. The strong ...
