Doubly heavy tetraquarks including one-pion exchange potential
Qi Meng, Emiko Hiyama, Makoto Oka +2
Spectrum of the doubly heavy tetraquarks is studied in a constituent quark model including one-pion exchange (OPE) potential. Central and tensor forces induced by OPE between two l…
Stable double-heavy tetraquarks: spectrum and structure
Q. Meng, E. Hiyama, A. Hosaka +5
Bound states of double-heavy tetraquarks are studied in a constituent quark model. Two bound states are found for isospin and spin-parity I(J^P ) = 0(1^+) in the bb\bar{u}\bar{d} c…
Compact pentaquark states predicted by a quark model
Qi Meng, Emiko Hiyama, Kadir Utku Can +4
Several compact pentaquark resonances are predicted in a potential quark model. The Hamiltonian is the best available one, which reproduces the masses of the low-lying…
Axial anomaly and hadronic properties in a nuclear medium
G. Fejos, A. Hosaka
We investigate meson and nucleon dynamics at finite baryon density and temperature by coupling the nucleon field and the omega meson to the three-flavor linear sigma model and calc…
Quark model estimate of hidden-charm pentaquark resonances
Emiko Hiyama, Atsushi Hosaka, Makoto Oka +1
A quark model, which reproduces the ground-state mesons and baryons, i.e., the threshold energies, is applied to the configurations, where is a light quark and~…
Effect of the final state interaction of on the photoproduction off nucleon
Shuntaro Sakai, Atsushi Hosaka, Hideko Nagahiro
We investigate the photoproduction off the nucleon with a particular interest in the effect of the final-state interaction (FSI) of the meson and nucleon based on…
