摘要：

We systematically investigate the mass spectrum, spatial configuration and magnetic moment of the ground and p-wave states [cu][(c) over bar(s) over bar] with various color-spin configurations in a multiquark color flux-tube model. Numerical results indicate that the state Z(cs)(4000)(+) can be described as the compact state [cu][(c) over bar(s) over bar] with 1(3)S(1). Its main color spin configuration is [cu]6(c)(1)[(c) over bar(s) over bar ]1/6(c) and its magnetic moment is 0.73 mu(N). The state Z(cs)(4220)(+) can be depicted as the compact state [cu][(c) over bar(s) over bar] with 1(1)P(1) (or 1(3)p(1)). Its main color-spin configuration is [cu]0/3(c) [(c) over bar(s) over bar]](0)(3c) (or [cu]0/3(c) [(c) over bar(s) over bar ]1/3(c)) and its magnetic moment is 0.12 mu(N) (or 0.64 mu(N)). The physical state should be the mixture of these two different color-spin configurations and deserves further investigation. In addition, we also predict the properties of the states [cu][(c) over bar(s) over bar] with other quantum numbers in the model.
