Magnetic moments of antidecuplet pentaquarks
نویسنده
چکیده
We analyze the magnetic moments of the exotic pentaquarks of the flavor antidecuplet in the constituent quark model for the case in which the ground state is in an orbital L = 0 or a L = 1− state. We derive sum rules for the magnetic moments. The magnetic moment of the Θ(1540) is found to be 0.38, 0.09 and 1.05 μN for J p = 1/2−, 1/2 and 3/2, respectively, which is compared with the results obtained in other approaches. PACS numbers: 14.20.Jn, 12.39.Mk, 13.40.Em, 12.39.-x

Magnetic moments of S-shell pentaquarks in the additive quark model
We discuss the magnetic moments of the recently discovered exotic baryons Θ+ and Ξ and their multiplet partners in the framework of a naive additive quark model. These baryons are set up as pentaquark states where four quarks and a single antiquark are located in their ground state orbit. The pentaquark states are classified as members of the flavor SU(3) octet and antidecuplet with spin-parity...
متن کاملMasses and magnetic moments of pentaquarks
We discuss the spectroscopy of the recently discovered exotic baryons as pentaquark qq̄ configurations. The ground state pentaquark configuration depends on the interplay between spin-flavor and orbital contributions to the mass operator. A simple calculation in an algebraic model gives a ground state antidecuplet pentaquark with isospin I = 0 and negative parity. The lowest pentaquark with posi...
متن کاملStructure of Light and Heavy Pentaquarks *
Light and heavy pentaquarks are described within a constituent quark model based on a spin-flavor hyperfine interaction. In this model the lowest state acquires positive parity. The masses of the light antidecuplet members are calculated dynamically using a variational method. It is shown that the octet and antidecuplet states with the same quantum numbers mix ideally due to SU(3) F breaking. M...
متن کاملDynamics of pentaquarks in constituent quark models: recent developments
Some recent developments in the study of light and heavy pentaquarks are reviewed, mainly within constituent quark models. Emphasis is made on results obtained in the flavor-spin model where a nearly ideal octet-antidecuplet mixing is obtained. The charmed antisextet is reviewed in the context of an SU(4) classification.

Dynamical calculations are performed for all isomultiplets of the flavour antidecuplet to which the newly discovered pentaquark Θ + belongs. The framework is a constituent quark model where the short-range interaction has a flavour-spin structure. In this model the lowest pentaquarks have positive parity. Each antidecuplet member is described by a variational solution with the Pauli principle p...
