Abstract: (Elsevier)
We propose an interacting quantum string theory of hadrons which has a close relation with quantum chromodynamics (QCD). Hadrons are constructed by attaching, massive, spin - 1 2 quarks, with internal symmetry, to the ends of strings. The string has independent longitudinal modes of oscillation which play a major role in the agreement with QCD. The string-string interactions are formulated in a new Hamiltonian formalism which allows strings to join or split only by quark-antiquark annihilation. Weak-electromagnetic gauge bosons are coupled to the flavor group of the quarks. By specializing to two dimensions, it is shown that quantum chromodynamics is equivalent to this string theory, in the sense that the mesonic and baryonic spectra, and the strong, weak and electromagnetic vertices for hadrons are identical in these two theories.- MODEL: HADRON
