Local meson-baryon coupled-channels potential for the Lambda(1405)
Kenta Miyahara, Tetsuo Hyodo, Wolfram Weise
A local coupled-channels Kbar N-pi Sigma-pi Lambda potential is constructed, equivalently reproducing the scattering amplitude in chiral SU(3) dynamics. By analyzing the wave funct…

Kenta Miyahara, Tetsuo Hyodo, Wolfram Weise
A Kbar N-pi Sigma-pi Lambda coupled-channel potential is constructed on the basis of chiral SU(3) dynamics. Several matching conditions are introduced to formulate an equivalent lo…
Theoretical study of the Lambda(1405) resonance in Xi_b^0 -> D^0 pi Sigma decay
Kenta Miyahara, Tetsuo Hyodo
We study the mechanism of the weak decay process of Xi_b^0 into D^0 with a meson-baryon pair. It is shown that the dominant component of the prompt weak decay produces the meson-ba…
Exotic Hadrons from Heavy Ion Collisions
ExHIC Collaboration, Sungtae Cho, Tetsuo Hyodo +12
Heavy ion collisions (HIC) at high energies are excellent ways for producing heavy hadrons and composite particles. With upgraded detectors at RHIC and LHC, it has become possible…
Few-body approach to structure of -nuclear quasi-bound states
Shota Ohnishi, Wataru Horiuchi, Tsubasa Hoshino +2
Structure of light antikaon-nuclear quasi-bound states, which consist of an antikaon and a few nucleons such as , , $\b…

Kenta Miyahara, Tetsuo Hyodo, Makoto Oka +2
Nonleptonic weak decays of Xi_c into pi^+ and a meson (M)-baryon (B) final state, MB, are analyzed from the viewpoint of probing S=-2 baryon resonances, i.e. Xi(1620) and Xi(1690),…

Akira Ohnishi, Kenji Morita, Kenta Miyahara +1
We investigate the and intensity correlations in high-energy heavy-ion collisions. First, we examine the dependence of the correlation on the interaction and…

Yuki Kamiya, Kenta Miyahara, Shota Ohnishi +4
The properties of the Lambda(1405) resonance are key ingredients for determining the antikaon-nucleon interaction in strangeness nuclear physics, and the novel internal structure o…

In this review we give a perspective of the theoretical work done recently on the interpretation of results from , , , weak decays into final states that contain i…
Composite nature of Lambda(1405) from the spacial structure of KbarN system
