A new tetra-quark interpretation of X(3872)

TL;DR

This paper proposes a novel tetra-quark model for X(3872), explaining its decay into different G-parity eigenstates by considering it as two degenerate tetra-quark mesons.

Contribution

It introduces a new tetra-quark interpretation of X(3872) involving degenerate mesons, providing a natural explanation for its decay modes.

Findings

X(3872) modeled as two degenerate tetra-quark mesons

Decays into two different G-parity eigenstates explained

Supports tetra-quark structure for exotic mesons

Abstract

A new tetra-quark interpretation of X(3872) is presented. In this model, X(3872) consists of two degenerate tetra-quark mesons, {[cn](cbar nbar) +- (cn)[cbar nbar]}_{I=0}, and, therefore, it is naturally understood that X(3872) decays into two different eigenstates of G-parity.
