摘要：

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/psi + 2 pi(3 pi) and X -> (D) over bar (0) + D-0 + pi(0) via the intermediate off-shell states X -> J/psi + rho(omega) and X -> (D) over bar + D*. For reasonable values of the size parameter Lambda(X) of the X(3872) we find consistency with the available experimental data.
