Abstract:

The X(3872) is a charmonium-like hadron with a mass close to the threshold. It was first observed in 2003 by the Belle Collaboration and confirmed shortly after by the CDF collaboration. The quantum numbers were recently determined by the LHCb experiment to be J^PC = 1⁺⁺³. Yet, the nature of the X(3872) is not fully understood. In future, lattice QCD calculations should be able to obtain observables and are expected to contribute to a better understanding of the X…
