TL;DR
This paper discusses possible interpretations of the recently observed charged charmonium-like state Z(3900), aiming to clarify its nature based on experimental observations by BESIII and Belle.
Contribution
It provides a comparative analysis of different theoretical interpretations of the Z(3900) state, highlighting potential explanations for its observed properties.
Findings
Z(3900) is confirmed by multiple experiments.
Several theoretical models are proposed for its interpretation.
The nature of Z(3900) remains uncertain, requiring further study.
Abstract
A new charged state, called has been recently observed by BESIII collaboration in 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).
