Description
In this talk, we review the recent result from ATLAS on the all-charm tetraquark search. It covers both the di-J/psi and J/psi+psi(4S) final states. Fitted resonance parameters from different fit models are compared. The ratio of branching fractions of X(6900) decaying into these two states is also provided. These results shed light on the nature of the all-charm tetraquarks.
