Interpreting Z(3900)

Abstract

A new charged state, called $Z_c(3900)$ has been recently observed by BESIII collaboration in $J/\psi {\pi }^{\pm }$ channel. The same has been confirmed by Belle (called Z(3894.5 in the Belle paper). In this short note we discuss probable interpretations of this charmonium like state which we call Z(3900).
