A study of ccc¯c¯ tetraquark decays in 4 muons and in D(⁎)D¯(⁎) at LHC

We 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...
