Figure 1: Spectrum of K J ∗ resonances from Ref. [7], with the vertical span of the boxes indicating
Figure 2: Comparison of m(J ψπ − ) in the m(K + π − ) ∈ [1085, 1265] MeV region between the background-subtracted data and simulated events weighted by moments models with J maxk = 2 and J maxk = 15.
Figure 3: Likelihood-ratio test for exotic significance. The data shows a 10σ deviation from the pseudoexperiments generated according to the null hypothesis (K J∗ -only contributions).
Figure 4: Background-subtracted 2D distribution of m(J/ψ π − ) versus m(K + π − ) in the region m(K + π − ) ∈ [745, 1545] MeV
