Strange pentaquarks with a hidden heavy quark-antiquark pair
Sachiko Takeuchi, Alessandro Giachino, Makoto Takizawa +2
The strange pentaquarks with hidden heavy quark pair ( and ) are investigated by the coupled-channel quark cluster model. Two types of the color-octe…
Di- structures from the quark Pauli-blocking effect
Sachiko Takeuchi, Atsushi Hosaka, Makoto Takizawa +1
The double-charmonium scattering states such as , , and are investigated by a simplified quark cluster model. It is found that the quark Pauli-principle ov…
X(3872) revisited: the roles of OPEP and the quark degrees of freedom
Sachiko Takeuchi, Yasuhiro Yamaguchi, Atsushi Hosaka +1
The is investigated by employing the quark-hadron hybrid model, that consists of the core, , , and two-meson states. Due to the…
The impact of quark many-body effects on exotic hadrons
Sachiko Takeuchi, Makoto Takizawa, Yasuhiro Yamaguchi +1
We investigate the exotic hadrons consisting of two light quarks and two heavy antiquarks, -. The spin-dependent term between quarks is known to give an attra…
Rich structure of the hidden-charm pentaquarks near threshold regions
Alessandro Giachino, Atsushi Hosaka, Elena Santopinto +3
The recent abundant observations of pentaquarks and tetraquarks by high-energy accelerator facilities indicate the realization of the conjecture by Gell-Mann and Zweig, and by De R…
Substructure of Multiquark Hadrons (Snowmass 2021 White Paper)
Nora Brambilla, Hua-Xing Chen, Angelo Esposito +27
In recent years there has been a rapidly growing body of experimental evidence for existence of exotic, multiquark hadrons, i.e. mesons which contain additional quarks, beyond the…
