Dual symmetric theory and the harmonic oscillator model of hadrons.

Abstract

The exciting activities the last two years :in the direction of dual resonance models,in particular the simple renormalization procedure £ow1d to eliminate the divergency :in loop graphs [12] and the symmetry properties encounter in the amplitudes which provides Ward-like identities [1.3] to be used to solve the problem of the ghost particles; and most of all the beautiful physical :interpretation discussed by Nielsen [14] and Susskind [15] exploting the conformal invariance of the theory,have :increased the hope of being on the right track for finding a general scheme to describe the physics or strong interactions.
