The X(3872) boson: Molecule or charmonium
It has been argued that the mystery boson X(3872) is a molecule state consisting of primarily D0D ∗0 + D 0 D∗0. In contrast, apparent puzzles and potential difficulties have been pointed out for the charmonium assignment of X(3872). We examine several aspects of these alternatives within our limited ability of quantitative reasoning. We point out that some of the observed properties of X(3872),...
متن کاملState of Charmonium
A theoretical explanation of the observed splittings among the P states of charmonium is given with the use of a nonsingular potential model for heavy quarkonia. We also show that the recently observed mass difference between the center of gravity of the PJ states and the P1 state of cc̄ does not provide a direct test of the color hyperfine interaction in heavy quarkonia. Our theoretical value f...
متن کاملar X iv : h ep - p h / 06 09 13 7 v 1 1 4 Se p 20 06 The double life of the X meson
Three years have passed since the BELLE discovery of the X(3872), and there are still (at least) two competing interpretations of this particle, which resembles a charmonium but behaves in a dramatic different way from it. Is X a molecule of two D mesons or a compact four-quark state? Are these two pictures really resolvable? The quantum mechanical intuition can also lead to more refined pictur...
متن کاملY ( 4260 ) and possible charmonium assignment
1550-7998=20 The newly reported Y(4260) becomes the second most massive state in the charmonium family. We argue that it displaces the 4415 as the (largely) 4s vector charmonium state, recall s d wave interference to explain the lack of a signal in e e ! hadrons and suggest some further study avenues that can exclude exotic meson assignments. The absence of a J= KK mode can be understood, beyon...
متن کاملCharmonium Spectrum and New Observed States
The linearity and parallelism of Regge trajectories is combined with a hyperfine splitting relation in multiplet to study charmonium spectrum. It is found that predictions to the spectrum of 1D multiplet could be made once another 1D state is confirmed. The newly observed X(3872), Y (3940), X(3940), Y (4260) and Z(3930) are studied within the charmonium framework. PACS numbers: 11.55.Jy, 12.39....
