Reggeon Nuclear Physics.|ˈrɛdʒeɪɒn|
[f. as prec. + -on1.]
(A particle represented by a) Regge pole or trajectory, or a virtual particle regarded as exchanged in the type of scattering they represent. Hence reggeˈonic a.
1964Physics Lett. IX. 269/1 Mandelstam has given some arguments that moving branching points may appear in a relativistic theory as a result of singularities to the right in the j-plane for particles with spin. These new singularities correspond to the production threshold of resonance states (reggeons) with negative orbital momenta. Ibid. XII. 153/2 If this fact is correct it would modify the reggeonic branch points and the elastic scattering asymptotic amplitude. 1974Physics Bull. May 206/4 High energy backward scattering is studied by (i) covariant reggeization techniques, (ii) the use of a super multiplet reggeon propagator model to generate polynomial residues. 1977P. D. B. Collins Introd. Regge Theory ii. 71 The power behaviour expected from the exchange of a Regge trajectory (sometimes called ‘Reggeon’)..may be contrasted with that from a fixed-spin (elementary) particle. 1978Nature 19 Jan. 214/2 Reggeons with arbitrarily high spin can be exchanged with equanimity. |
