Quark-model search for compact pentaquark states

Emiko Hiyama, Atsushi Hosaka, Makoto Oka +1

A potential quark model is used to search for a , pentaquark state that has recently been observed experimentally by the LHCb collabora…

Linear realization of SU(3) parity doublet model for octet baryons with bad diquark

Bikai Gao, Atsushi Hosaka

We construct a linear parity doublet model for octet baryons. Our model employs the and chiral representations…

A Lagrangian for the Chiral (1/2,0) + (0,1/2) Quartet Nucleon Resonances

V. Dmitrasinovic, A. Hosaka, K. Nagata

We study the nucleon and three N* resonances' properties in an effective linear realization chiral SU_L(2) x SU_R(2) and U_A(1) symmetric Lagrangian. We place the nucleon fields in…

Path-integral approach in a chiral quark-diquark model to the nucleon structure and interactions

Keitaro Nagata, Atsushi Hosaka

We study the structure of the nuclear force by using a path-integral hadronization approach in a chiral quark-diquark model. After the construction of the chiral quark-diquark mode…

Chiral symmetry aspects of positive and negative parity baryons

A. Hosaka, D. Jido, M. Oka

Chiral symmetry aspects for baryon properties are studied. After a brief discussion on general framework, we introduce two distinctive chiral group representations for baryons: the…

Flavor SU(3) breaking effects in the chiral unitary model for meson-baryon scatterings

T. Hyodo, S. I. Nam, D. Jido +1

We examine flavor SU(3) breaking effects on meson-baryon scattering amplitudes in the chiral unitary model. It turns out that the SU(3) breaking, which appears in the leading quark…
