Abstract

In this Letter, we propose interpolating currents for the X(3872) resonance, and show that, in the heavy quark limit of QCD, the X(3872) state should have degenerate partners, independent of its internal structure. Magnitudes of possible I= 0 and I= 1 components of the X(3872) are also discussed. © 2013 Elsevier B.V.
