Abstract
We explore the consequences of treating the meson as a tetraquark bound state. As dynamical framework we employ a relativistic constituent quark model which includes infrared confinement in an effective way. We calculate the decay widths of the observed channels and via the intermediate off-shell states and . For reasonable values of the size parameter of the we find consistency with the available experimental data. We also discuss the possible impact of the in a s-channel dominance description of the dissociation cross section.
