Pentaquarks in SU(3) quark model
Hungchong Kim, Yongseok Oh
Based on the flavor SU(3) symmetry, we classify all the possible pentaquark baryons made of four quarks and one antiquark. In particular, we present possible multiplets of pentaqua…
Decay modes of ideally mixed narrow pentaquark states
Su Houng Lee, Hungchong Kim, Yongseok Oh
We investigate the decay modes of pentaquark baryons for both the antidecuplet and the octet states, which were recently claimed by Close and Dudek to be potentially narrow due to…
Vector meson photoproduction processes near threshold
Yongseok Oh
We discuss the photoproduction processes of light vector mesons (, , and ) from the nucleon near threshold. We first develop a simple model based on meson exchanges which…
Electromagnetic production of vector mesons at low energies
Yongseok Oh, Alexander I. Titov, T. -S. Harry Lee
We have investigated exclusive photoproduction of light vector mesons (, and ) on the nucleon at low energies. In order to explore the questions concerning the so-called…
Phi-meson photoproduction and strangeness of the nucleon
Yongseok Oh
The polarization observables in phi photoproduction are suggested for probing the nucleon strangeness. Based on models for phi photoproduction, some double polarization observables…
Soliton Structure of Heavy Baryons
D. -P. Min, Y. Oh, B. -Y. Park +1
Heavy-quark baryons are described as a bound heavy-meson-soliton system in a Lagrangian that combines chiral symmetry and heavy-quark symmetry. We introduce a ``Wess-Zumino type" t…
