Abstract

We discuss the production mechanism of fully charm tetraquark, observed last year by the LHCb at M = 6.9 GeV in the J/ψJ/ψ channel. Both single parton scattering (SPS) and double parton scattering (DPS) mechanisms are considered. We calculate the distribution in the invariant mass of the four-quark system, M4c, for SPS and DPS production of ccc¯c¯ in the kt-factorization approach. We present transverse momentum distribution in pt,4c for ccc¯ c¯ system in a mass window around tetraquark mass. The calculation of the SPS g ∗ g ∗ → T4c(6900) fusion mechanism is performed in the kT -factorization approach assuming different spin scenarios (0 + and 0 −).
