Description
We explore the consequences of treating the X(3872) 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 X→J/ψ+2π(3π) and X→D-bar0+D0+π0 via the intermediate off-shell states X→J/ψ+ρ(ω) and X→D-bar+D*. For reasonable values of the size parameter ΛX of the X(3872) we find consistency with the available experimental data.
