Spectroscopy of all charm tetraquark states

The mass spectra of all-charm tetraquark states with the [cc][$\bar{c}\bar{c}$] quark configuration are investigated. coulomb plus linear potential is used in conjunction relativistic correction term $\mathcal{O}(\frac{1}{m})$. To determine fitting parameters for tetraquarks [cc][$\bar{c}\bar{c}$], we first calculate charmonia [c$\bar{c}$] and its decay constants ($f^{2}_{P/V}$). We estimated masses their ground radially excited states. For states, also included spin-spin, spin-orbital, tensor interactions. produced this study reasonably consistent experimental theoretical predictions made by others, whilst previous predictions. propose that X(6900) state, which has a range 6.2 - 6.9 GeV was recently detected LHCb, quantum numbers $0^{-+}$, $1^{-+}$, $2^{-+}$ belongs to P-wave all-cham state.
