Exactly solvable cases of Regge poles from mandelstam representation

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Starting form the Mandelstam representation in potential scattering, explicit examples are given for which the Regge functionR(s, λ) is known exactly. In particular, a symmetry property ofR(s, λ) at integral λ is derived. The nature of « kinematical » and « dynamical » Regge poles is discussed in some detail. Finally, the potentials responsible for the various cases are written down in Born approximation.

Riassunto

Partendo dalla rappresentazioue di Mandelstam nello scattering di Potenziale, si danno esempi espliciti in oui è esattamente nota la funzione di Regge R(s, λ). In particolare si deduce una proprietà di simmetria diR(s, λ) per λ intero. Si discute con qualche dettaglio la natura dei poli di Regge « cinematici » e « dinamici ». In fine si scrivono nell’approssimazione di Born i potenziali che generano i vari casi.
