The X(3872) as a charmonium state plus an extra component due to continuum coupling effects

We discuss the results of an unquenched quark model (UQM) calculation of the self energy corrections to charmonium spectrum due to the coupling to the meson-meson continuum. In our approach, the effects of quark-antiquark pairs are introduced explicitly into the QM through a 3P0 quark-antiquark pai...
