A Pentaquark Model for Λ(1405)
نویسنده
چکیده
We study a pentaquark model of the negative parity hyperon Λ(1405). We choose a specific quark configuration for trial, and use the perturbative chiral quark model extended to four quarks and one anti-quark system. We calculate a σ-term and a scalar form factor of the hyperon and demonstrate their usefulness to study the nature of the hyperon.

A pentaquark picture of Λ(1405)
We test a pentaquark model of the negative parity hyperon Λ(1405). We use a model where valence four quarks and one antiquark move in a potential relativistically and interact with each other and themselves through gluon and NG boson. Fall-apart decay rate of the system is studied and strong model dependence is pointed out.

We test a pentaquark model of the negative parity hyperon Λ(1405). We use the model where valence four quarks and one antiquark move in a potential relativisticaly and interact with themselves and each other through gluon and NG boson. We calculate mass shift of the system and find that there are two Λ(1405) with almost degenerate mass: one flavor singlet and one flavor octet. We calclate also ...

We perform a five-body calculation for pentaquark (q 4 ¯ q) state of Λ(1405) as well as the three-body calculations for the ground state baryons and the Λ(1405), and two-body calculations for mesons. The hamiltonian, which reproduces reasonably well the energies of ground state baryons (N, Λ, Σ, Ξ and ∆) and mesons (π, K, ρ, K *), includes kinetic energy of semi-relativistic form, linear confin...
متن کاملElectric Mean Squared Radii of Λ(1405) in Chiral Dynamics
The electric mean squared radii 〈r〉E of Λ(1405) are calculated in the chiral unitary model. We describe the Λ(1405) as a dynamically generated resonance fully in the octet meson and octet baryon scattering. We also consider “Λ(1405)” as a bound state of K̄N . For the later “Λ(1405),” we obtain negative and larger absolute value of electric mean squared radius than that of ordinary baryons, which...
متن کاملPentaquark Θ(1540) production in γN → KKN Reactions
Abstract The recent developments in the search of exotic pentaquark hadrons are briefly reviewed. We then focus on investigating how the exotic pentaquark Θ(1540) baryon production can be identified in the γN → KKN reactions, focusing on the influence of the background (non-Θ production) mechanisms. By imposing the SU(3) symmetry and using various quark model predictions, we are able to fix the...
