Possibility of s-wave pion condensates in neutron stars revisited
A. Ohnishi, D. Jido, T. Sekihara +1
We examine possibilities of pion condensation with zero momentum (s-wave condensation) in neutron stars by using the pion-nucleus optical potential U and the relativistic mean fiel…
Electric Mean Squared Radii of Lambda(1405) in Chiral Dynamics
T. Sekihara, T. Hyodo, D. Jido
The electric mean squared radii <r^2>_E of Lambda(1405) are calculated in the chiral unitary model. We describe the Lambda(1405) as a dynamically generated resonance fully in the o…
The structure of N(1535) in the aspect of chiral symmetry
Daisuke Jido, Tetsuo Hyodo, Atsushi Hosaka
The structure of N(1535) is discussed in dynamical and symmetry aspects based on chiral symmetry. We find that the N(1535) in chiral unitary model has implicitly some components ot…
Electromagnetic mean squared radii of Lambda(1405) in chiral dynamics
T. Sekihara, T. Hyodo, D. Jido
The electromagnetic mean squared radii, <r^2>_E and <r^2>_M, of Lambda(1405) are calculated in the chiral unitary model. We describe the excited baryons as dynamically generated re…
Origin of resonances in the chiral unitary approach
Tetsuo Hyodo, Daisuke Jido, Atsushi Hosaka
We study the origin of the resonances associated with pole singularities of the scattering amplitude in the chiral unitary approach. We propose a "natural renormalization" scheme u…
Lambda(1405) in chiral SU(3) dynamics
Tetsuo Hyodo, Wolfram Weise, Daisuke Jido +2
We discuss several aspects of the Lambda(1405) resonance in relation to the recent theoretical developments in chiral dynamics. We derive an effective single-channel KbarK N intera…
