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…

Construction of a local barK N-pi Sigma-pi Lambda potential and composition of the Lambda(1405)
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…
