A relativistic quark model with infrared confinement and the tetraquark state

Understand

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 hadronic decay widths of the observed channels.
• For reasonable values of the size parameter of the X(3872) we find consistency with the available experimental data.
