Regge Nuclear Physics.|ˈreɪdʒeɪ|
The name of T. E. Regge (b. 1931), Italian physicist, used attrib. to designate certain concepts in the theory of the scattering of sub-atomic particles, as Regge pole, a pole of a complex function relating the scattered amplitude of partial waves to angular momentum; Regge trajectory, a path traced in the complex angular momentum plane by a Regge pole as the energy varies; esp. a plot of spin against the square of the rest mass for a group of particles.
1961Physical Rev. Lett. VII. 394/2 We may satisfy Feynman's principle therefore by postulating that all poles of the S matrix are of this type (Regge poles). 1962Ibid. VIII. 41/2 Each point is supposed to lie on a Regge trajectory. 1962Physical Rev. CXXVI. 2204/2 This perturbation theory behavior is very different from that of the Regge case. Ibid., Strongly interacting particles may exhibit the Regge behavior. 1973[see pole n.2 10]. 1973B. H. Bransden et al. Fundamental Particles viii. 163 (caption) The Regge trajectories of some meson states. Mesons differing in spin by one unit appear to lie on the same Regge trajectory. 1973L. J. Tassie Physics Elem. Particles xii. 170 Most work on Regge theory is concerned with describing collision processes, and in this respect the Regge pole model is not a theory with a high predictive power. 1975Sci. Amer. Feb. 62/3 The Regge trajectories turn out on observation to be nearly linear, meaning that the angular momentum of the particles on a particular trajectory is given to a good approximation by a linear function of the mass of the particle squared. 1977P. D. B. Collins Introd. Regge Theory ii. 69 When such a Regge pole occurs for a physical integer value of l it will correspond to a physical particle or resonance. 1977Nature 21 July 207/2 Hadrons on the same Regge trajectory have a remarkably simple relation between mass and angular momentum: J = α′M2 + α0, where J is the total angular momentum of the hadron, M is its mass and α′ and α0 are called the Regge ‘slope’ and ‘intercept’ respectively. |
