摘要：

We explore the influence of open-charm channels on charmonium properties and profile the 1(3)D(2), 1(3)D(3), and 2(1)P(1) charmonium candidates for X(3872). The favored candidates, the 1(3)D(2) and 1(3)D(3) levels, both have prominent radiative decays. The 1(3)D(2) might be visible in the D-0(D) over bar*(0) channel, while the dominant decay of the 1(3)D(3) state should be into D (D) over bar. We propose that additional discrete charmonium levels can be discovered as narrow resonances of charmed and anticharmed mesons.
