Absence of Macdowell doublets, duality solutions for baryons and backward pi N scattering at 6 GeV/c

An attempt is made to compare restrictions on baryon-exchange Regge residues demanding absence of MacDowell doublets and incorporating an approximate duality solution for the decuplet exchange with experimental data on pi N backward cross sections and polarizations at p/sub lab/=6 GeV/c. Although th...

Sumario:An attempt is made to compare restrictions on baryon-exchange Regge residues demanding absence of MacDowell doublets and incorporating an approximate duality solution for the decuplet exchange with experimental data on pi N backward cross sections and polarizations at p/sub lab/=6 GeV/c. Although the gross features of cross sections and polarizations can be obtained from N/sub alpha /, Delta /sub delta /, Delta /sub beta / exchanges, substantial contributions of another nature are needed to describe all details of the data.
