Empirical light meson trajectories: radial P-3(2), P-3(0), F-3(2)

摘要

Candidate light meson states are selected to form linear trajectories in squared mass m(2) vs. radial excitation number N. The most numerous candidates have J (PC) = (even)(++) and J less than or equal to 2: namely, (3)p(2), (PO)-P-3 and F-3(2). About 40 states are assembled into 11 trajectories distinguished by four flavors: f, a, K and f '; no candidates appeared for F-3(2) : K. From these data the universal slope of the Veneziano model emerges as A = dm(2)/dN = 1.04 +/- 0.01 GeV2. (C) 2001 Elsevier Science B.V. All rights reserved. [References: 52]
