释义 | Reggen. Particle Physics. 1. Regge pole n. a pole (pole n.2 13) of a complex function that arises in the scattering of a particle, relating the angular momentum of the incident particle to the scattering amplitude.Such a pole traces a path in the complex angular momentum plane as the energy of the incident particle increases, and represents a (real or virtual) particle exchanged in the interaction.

Lett. 7 394/2 We may satisfy Feynman's principle therefore by postulating that all poles of the S matrix are of this type (Regge poles). 1977 P. 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. 1995 S. Weinberg Quantum Theory of Fields (2000) I. x. 468 High energy behavior is usually inferred from Regge pole theory. 2008 Jrnl. Physics: Conf. Ser. 50 160 Regge poles arise when one does an angular momentum decomposition of scattering amplitudes. 2. Regge trajectory n. a path traced in the complex angular momentum plane by a Regge pole as the energy of the incident particle varies; (also) a graph (typically an approximate straight line) of the spins of particles against the squares of their rest masses.

Lett. 8 41/2 Each point is supposed to lie on a Regge trajectory. 1975 Sci. 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. 1995 S. Weinberg Quantum Theory of Fields (2000) I. v. 468 A set of ‘Regge trajectories’, each representing the exchange of an infinite family of different one-hadron states in the collision process. 2007 Physics Lett. B. 655 284/2 We will find the closest quantum state to the leading classical Regge trajectory. 3. attributive. Designating the theory of the scattering of subatomic particles developed by Regge; of or relating to this theory. ΚΠ 1962 Physical Rev. 126 2204/2 This perturbation theory behavior is very different from that of the Regge case. 1973 L. 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. 1989 Physics Lett. B. 225 437 Using general principles like Regge behaviour and positivity we derive simple parametrizations for quark and gluon polarized distribution function. 2004 A. Watson Quantum Quark 417 Regge theory, a framework for describing strong interaction scattering data.
