Included are the open-charm pseudoscalar-vector and vector-vector channels, the most important of which is the S-wave $\\bar{D}^{*0}D^{0}$ + $D^{*0}\\bar{D}^{0}$ channel, which practically coincides with the X(3872) structure. The two free parameters of the model are tuned so as to roughly reproduce the $\\chi_{c1}(3511)$ mass as well as the enhancement just above the $\\bar{D}^{*0}D^{0}","authors_text":"E. van Beveren, G.
