Title: Property of cn-n-barc-bar System in U-tilde(12)-Scheme and X(3872)/Y(3940)

Abstract

The properties of four quark cn-n-barc-bar states are investigated as cn di-quark and n-barc-bar di-antiquark system in U-tilde(12)-classification scheme of hadrons. We consider the negative-parity di-quark and di-antiquark in ground states, and the properties of X(3872) and Y(3940) are consistent, respectively, with those of the JPC = 1++ and 2++ states from these negative-parity di-quark and di-antiquark. Their narrow-widths are explained from a kind of conservation law, called {rho}3-line rule. The properties of ground-state cs-s-barc-bar system are also predicted in this scheme.
