Description
The discovery of narrow resonant structures in the di-J/psi and psi-psi(2S) mass spectra suggests the existence of fully-charmed tetraquark states. This report presents an amplitude analysis of ATLAS data in these channels to study the properties of these exotic resonances. By performing a simultaneous fit to the mass and angular distributions, we measure the masses and widths of the observed states, and also constrains the possible spin-parity configurations, helping to elucidate the nature of the X(6900) and other nearby structures.
