“…Thus, in a subsequent paper we will focus on threshold effects and the decays of states close to open and hidden-flavor decay thresholds. This procedure will not only have an effect on the widths, but also on the mass values [47].…”

In this paper, we calculate mass and probability fractions of meson-meson components of X(3872) in an unquenched quark model. Different from most of other unquenched quark models, the quark pairs creation operator from 3 P0 is modified by considering effects of the created quark pair energy and separation between the created quark pair and the valence quark-pair. In the calculation, all the wavefunctions of mesons and the relative motion between two mesons are obtained by solving the corresponding Schrödinger equation with the help of gaussian expansion method. The multichannel coupling of quark-antiquark state with possible meson-meson states are performed. The results show that the X(3872) can be described as a mixing state of dominant charmonium state (70%) and meson-meson components (30%).
