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…

Calculation of Dissociation Temperature of Nucleon Using Gaussian Expansion Method
Peng Cheng, Qi Meng, Qian Wu +2
The first study of the dissociation temperature of nucleon in hot QCD medium in the framework of constituent quark model is presented. The temperature-dependent potential energy of…
