Charmonium possibility of X (3872)

摘要

Properties of Regge trajectories for charmonium are studied. Possible interpretations and their implications to newly observed X(3872) are examined. It is found that the mass of X (3872) is consistent with the 1(++) 2(3) P-1 and the 2(-+) 1(1) D-2 charmoniurn states. (c) 2007 Elsevier B.V. All rights reserved.
