"Figure 5 (Regge fit)" of "Observation of a family of all-charm tetraquarks"
Abstract
Masses and widths obtained from the Regge trajectory fit for the X states shown in Fig. 5 (statistical uncertainties only). The fit parameters are $\beta_0 = -9.374 \pm 0.355$ and $\beta = 0.241 \pm 0.008$, with fit quality $\chi^2/\mathrm{n_{bin}} = 119/113$ below 9 GeV, $\chi^2/\mathrm{n_{bin}} = 62/65$ below 7.8 GeV, where $\text{n}_{\text{bin}}$ is the number of nonzero bins.
