dc.description.abstractWe perform a quantitative analysis of the decays of ccc¯c¯ tetraquarks with JPC=0++,2++ into 4 muons and into hidden- and open-charm mesons and estimate, for the first time, the fully charmed tetraquark decay width. The calculated cross section upper limit is ∼39(780) fb for the 4 muons channel, and ∼42(616) pb for the ⁎⁎D(⁎)D¯(⁎)→eμ channel, in the 0++(2++) case. Decay widths depend upon the additional parameter ξ=|ΨT(0)|2/|ΨJ/ψ(0)|2, which can be computed with a considerable error. We find Γ(0++)∼Γ(2++)=97±30. On the basis of our results and with the present sensitivity, LHCb should detect both 0++ and 2++ fully-charmed tetraquarks.en
