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…
Axial anomaly effect on three-quark and five-quark singly heavy baryons
Hiroto Takada, Daiki Suenaga, Masayasu Harada +2
Effects of the axial anomaly on the mass spectrum of singly heavy baryons (SHBs) is studied in terms of the chiral effective theory based on the chiral linear representati…
Quark Confinement for Multi-Quark Systems -- Application to Fully-Charmed Tetraquarks
Guang-Juan Wang, Makoto Oka, Daisuke Jido
A new color basis system and confinement mechanism for multi-quark systems are proposed according to the string-type picture of QCD. The color string configurations in the strong c…
New insight into the exotic states strongly coupled with the from the
Guang-Juan Wang, Zhi Yang, Jia-Jun Wu +2
We have investigated the internal structure of the open- and hidden-charmed (/) molecules in the unified framework. We first fit the experimental lineshape of the…
Axial anomaly effect to the chiral-partner structure of diquarks at high temperature
Daiki Suenaga, Makoto Oka
Masses of positive-parity and negative-parity diquarks are investigated at finite temperature with a quark chemical potential. We employ the three-flavor Nambu-Jona-Lasinio model,…
Spin-Flavor SU(6) Symmetry for Baryon-Baryon Interactions
Makoto Oka
Short-range parts of the baryon-baryon () interactions are analyzed from the spin-flavor symmetry viewpoint. Due to the Pauli princip…
