Electric 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 کاملKei Moriya IU Properties of the Λ(1405) Hyperon Studied at CLAS Using Photoproduction
The internal structure of the Λ(1405) hyperon has remained an unresolved mystery in hadron physics for decades. Observed as a resonance in Σπ just below the N-K threshold , it is the first excited Λ state; yet the nature of this resonance, where it belongs in the hierarchy of hyperons, and some of its basic properties, remain unsettled. In previous experiments, the invariant mass spectrum (line...
متن کاملPossible Hadronic Molecule Λ(1405) and Thermal Glueballs in SU(3) Lattice QCD
We aim to construct quark hadron physics based on QCD. First, using lattice QCD, we study mass spectra of positive-parity and negative-parity baryons in the octet, the decuplet and the singlet representations of the SU(3) flavor. In particular, we consider the lightest negative-parity baryon, the Λ(1405), which can be an exotic hadron as theNK̄ molecular state or the flavor-singlet three-quark s...
متن کاملA Comment on the Radiative Decays of the Λ ( 1405 )
We examine the radiative decays of the Λ(1405) to octet baryons, Λ(1405) → Λγ and Λ(1405) → Σ0γ. In the limit of SU(3) symmetry the decay rates for these two modes are related, and we compute the leading correction to the relation in chiral perturbation theory. Such measurements will allow the sign of the strong coupling gΛ∗ to be determined. The SU(3) violating radiative decay to the baryon de...
متن کاملChiral Dynamics, Structure of Λ(1405), and K̄n Phenomenology
We investigate the structure of the Λ(1405) resonance and K̄N phenomenology in the perspective of chiral SU(3) dynamics. Utilizing the chiral coupled-channel approach which well describes the K̄N scattering observable, we perform three different analyses to clarify the structure of the Λ(1405) resonance. The results consistently indicate the meson-baryon molecule picture of the Λ(1405). We argue ...
