Abstract
We present the analysis of Ref.[1] of the radial (n) and angular-momentum (J) Regge trajectories for all light-quark meson states listed in the Particle Data Tables. The parameters of the trajectories are obtained with linear regression, with weight of each resonance inversely proportional to its half-width squared, (\Gamma/2)^2. The joint analysis in the (n,J,M^2) Regge plane indicates, at the 4.5 standard deviation level, that the slopes in n are larger from the slopes in J. Thus no strict universality of slopes occurs in the light non-strange meson sector. We also extend our analysis to the kaon sector.

We extend our analysis to the kaon sector
We considered a joint fit with the formula MX2 (n, J) = MX2 (0, 0) + nμ2 + Jβ2, with the result MX2 (n, J) = (−1.25(4) + 1.38(4)n + 1.12(4)J) GeV2, which means a difference between the radial and the angular-momentum slopes at a statistically significant level of 4.5 standard deviations

[1] of the radial (n) and angular-momentum (J) Regge trajectories for all light-quark meson states listed in the Particle Data Tables. The parameters of the trajectories are obtained with linear regression, with weight of each resonance inversely proportional to its half-width squared, (Γ/2)2.
