DUAL RESONANCE MODEL WITH QUARK SPIN.
Chicago Univ., Ill. Enrico Fermi Inst. Chicago Univ., Ill. Dept. of Physics, M Yoshimura · 1970
We present a dual resonance model with nontrivial quark spin factors.An amplitude is found which satisfies factorization and eliminates the parity doubling ghosts.An application to 7TT elastic scattering indicates that the positivity condition is not met on the first daughter trajectory if one assumes realistic values for the mass and intercept.+Supported in part by the U.
