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

Bikai Gao, Atsushi Hosaka

We construct a linear $S U (3)_{L} \times S U (3)_{R}$ parity doublet model for octet baryons. Our model employs the $(3, 3 ˉ) + (3 ˉ, 3)$ and $(3, 6) + (6, 3)$ chiral representations…

Quark-model search for compact $c c ˉ u d s$ pentaquark states

Emiko Hiyama, Atsushi Hosaka, Makoto Oka +1

A potential quark model is used to search for a $P_{c c ˉ s}^{0} = (c c ˉ u d s)^{0}$ , $J^{P} = 1/ 2^{-}$ pentaquark state that has recently been observed experimentally by the LHCb collabora…
