A model for a Regge trajectory compatible with the threshold behavior required by unitarity and asymptotics in agreement with analyticity constraints is given in explicit form. Breaking of exchange degeneracy is studied in the model and its effect on both masses and widths is determined.

Abstract
A model for a Regge trajectory compatible with the threshold behavior required by unitarity and asymptotics in agreement with analyticity constraints is given in explicit form. Breaking of exchange degeneracy is studied in the model and its effect on both masses and widths is determined.File in questo prodotto:
