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…
Testing the tetraquark structure for the resonances in low-lying region
Hungchong Kim, K. S. Kim, Myung-Ki Cheoun +2
Assuming four-quark structure for the resonances in low-lying region, we calculate their masses using the color-spin interaction. In specific, the hyperfine masses of the color…
Two, three, many body systems involving mesons. Multimeson condensates
E. Oset, M. Bayar, A. Dote +8
In this talk we review results from studies with unconventional many hadron systems containing mesons: systems with two mesons and one baryon, three mesons, some novel systems with…
Narrow bound states of the DNN system
E. Oset, M. Bayar, C. W. Xiao +3
We report on a recent calculation of the properties of the system, a charmed meson with two nucleons. The system is analogous to the system substituting a strange…
Possible molecular bound state
Wakafumi Meguro, Yan-Rui Liu, Makoto Oka
Possible hadronic molecule is investigated in the one-pion-exchange potential model. In the study with this model, the heavier meson exchange effects are encoded into a ph…
Chiral Symmetry of Nucleon Resonances in QCD sum rules
T. Nakamura, P. Gubler, M. Oka
The QCD sum rule approach is employed in order to study chiral properties of positive- and negative-parity nucleon resonances. It is pointed out that nucleons with an ``exotic'' ch…
