The nature of the Λ(1405) resonance in chiral dynamics
Abstract The Λ ( 1405 ) baryon resonance plays an outstanding role in various aspects in hadron and nuclear physics. It has been considered that the Λ ( 1405 ) resonance is generated by the
KKN molecular state in a three-body calculation
A KKN system with I=1/2 and J{sup P}=1/2{sup +} is investigated with nonrelativistic three-body calculations by using effective KN and KK interactions. The present investigation suggests that a
Chiral Symmetry of Baryons
We study chiral symmetry aspects of the positive and negative parity baryons by identifying them with linear representations of the chiral group SU (N f ) ⊗ SU (N f ). It is shown that there are two
Compositeness of dynamically generated states in a chiral unitary approach
The structure of dynamically generated states in the chiral unitary approach is studied from a viewpoint of their compositeness. We analyze the properties of bound states, virtual states, and
In-medium $\eta^{\prime}$ mass and $\eta^{\prime}N$ interaction based on chiral effective theory
The in-medium eta' mass and the eta'N interaction are investigated in an effective theory based on the linear realization of the SU(3) chiral symmetry. We find that a large part of the eta' mass is
$\eta$η-nucleus interaction from the d + d reaction around the $\eta$η production threshold
Abstract.The $\eta$η mesic nucleus is considered to be one of the interesting exotic many-body systems and has been studied since the 1980s theoretically and experimentally. Recently, the formation
Nuclear bound state of eta'(958) and partial restoration of chiral symmetry in the eta' mass
The in-medium mass of the $\eta^{\prime}$ meson is discussed in a context of partial restoration of chiral symmetry in nuclear medium. The $\eta^{\prime}$ mass is expected to be reduced by order of
Formation of \eta -Mesic Nuclei
In this paper, we briefly introduce the interests and the recent research activities on the \eta -mesic nuclei. We also mention the activities on the \eta ' (958)-mesic nucleus formation.
Exotic Hadrons from Heavy Ion Collisions
High energy heavy ion collisions are excellent ways for producing heavy hadrons and composite particles, including the light (anti)nuclei. With upgraded detectors at the Relativistic Heavy Ion
