Exotic charmonium-like spectroscopy at LHCb: a study of the X(3872) and of the Z(4430)-
Abstract
I will report on the recent LHCb results on the evidence for the decay X(3872)→(2S) γ, and on the improved measurement of the mass and width of the Z(4430)-, the determination of its quantum numbers and the observation of its resonant character.
