Analytic Solution of Ground State for Coulomb Plus Linear Potential

W. Q. Chao, C. S. Ju

The newly developed single trajectory quadrature method is applied to solve the ground state quantum wave function for Coulomb plus linear potential. The general analytic expressio…

$π - π$ Scattering Lengths and Chiral Condensate in NJL Model

Mei Huang, Pengfei Zhuang, Weiqin Chao

Within the general framework of SU(2) Nambu-Jona-Lasinio model beyond mean-field approximation, the S-wave $π - π$ scattering lengths $a_{0}^{0}$ and $a_{0}^{2}$ are calculated. The numeric…

GCP Code Applied in $J / ψ$ Production and Absorption

Xiao-Xia Yao, Wei-Qin Chao, Yang Pang

Using the General Cascade Program(GCP), the production and absorption of $J / ψ$ in p-A and A-A collisions have been studied. Nucleon absorption mechanism and comover absorption mech…

Different Nuclear Dependence of $J / ψ$ and $ψ^{'}$ Production in p-A and A-p Collisions

Yong-Bin He, Wei-Qin Chao, Chong-Shou Gao

While presently available p-A data observe that the nuclear dependence of $J / ψ$ and $ψ^{'}$ production is the same within errors, we show that different nuclear dependence of…
