抄録

The measured large value of Δσ_L for pp scattering must be interpreted as a violation of strong exchange degeneracy(SEXD) of A_1 and Z. A SEXD violating A_1-Z contribution to Im U_0 provides a fine representation of Δσ_L for p_L ≥ 3 GeV/c. The Legendre coefficients of this amplitude draw the loops on the Argand diagram. We discuss a similarity between the top positions of them and the possible dibaryon resonances, and a duality scheme due to lowlying trajectories.
