Regge trajectory

Regge trajectory

[′reg·ə trə‚jek·trē]
(particle physics)
The path followed by a Regge pole in the complex angular momentum plane as the center-of-mass energy is varied.
The relationship between the spin and mass of a sequence of hadrons, with successive hadrons increasing by 2 in spin and also increasing in mass, but with the same values of other quantum numbers; the hadrons are thought to correspond to energies at which a Regge pole passes near positive integers (or half integers).

The comparison between the meson and baryon masses of the [rho]/[omega] Regge trajectory with the spin-3/2 [DELTA] trajectory is shown in Figure 3.
This equation is the Regge trajectory like (J - [M.sup.2]) behavior seen in Chew-Fraustchi plots for unstable quark spin families (see [12] for some examples).
This proposition results in Regge trajectory like behavior.
Ne'eman and Sijacki [3] use the SL(4, R) group and spin (1/2, 3/2, 5/2, etc.) to produce the Regge trajectory like behavior of quark particle masses suggesting the possibility that mass may be spin quantized.
