Abstract
Dual resonance models (DRM) lack unitarity and cannot incorporate the pomeron. Higher order corrections (loop terms) are expected to cure these defects [1]. I want to summarize the results [2] in simple terms stressing particularly the similarity between the loop and the original tree expressions.
Seminar given at XI. Internationale Universitätswochen für Kernphysik, Schladming, February 21—March 4, 1972.
