Non-interacting KN contribution in the QCD sum rule for the pentaquark Theta^+(1540)
Youngshin Kwon, Atsushi Hosaka, Su Houng Lee
We perform a QCD sum rule analysis for the pentaquark baryon Theta^+ with the non-interacting contribution treated carefully. The coupling of the Theta^+ current to the s…
Phenomenology of spin 3/2 baryons with pentaquarks
Tetsuo Hyodo, Atsushi Hosaka
We examine several assignments of spin and parity for the pentaquark Theta+ state (J^P=1/2^{+,-}, 3/2^{+,-}) in connection with known baryon resonances. Assuming that the Theta+ be…
Photoproduction of Lambda(1520,3/2^-)
Seung-Il Nam, Atsushi Hosaka, Hyun-Chul Kim
We investigate the photoproduction of Lambda(1520,3/2^-) via the gamma N -> K Lambda^* reaction using the Born approximation and the Rariata-Schwinger vector-spinor field for the s…
Dynamical baryon resonances from chiral unitarity
A. Ramos, C. Bennhold, A. Hosaka +6
We report on the latests developments in the field of baryonic resonances generated from the meson-baryon interaction in coupled channels using a chiral unitary approach. The colle…
