Coupled-channel model for charmonium levels and an option for X(3872)
arXiv:hep-ph/0506270 · doi:10.1103/PhysRevD.72.034010
Abstract
The effects of charmed meson loops on the spectrum of charmonium are considered, with special attention paid to the levels above open-charm threshold. It is found that the coupling to charmed mesons generates a structure at the D \bar{D}* threshold in the 1++ partial wave. The implications for the nature of the X(3872) state are discussed.
