For the deformation parameter q a root of unity, in addition to the relation of such values of q with the rational conformal field theory, the Fock space of each oscillator mode in the Fubini-Veneziano operator formulation becomes truncated. Thus, based on general physical grounds, the resulting spin-(mass)2 relation is expected to be below the usual linear trajectory. For such specific values of q, we find that the linear Regge trajectory turns into a square-root trajectory as the mass increases.147-152engNew phenomenon of nonlinear Regge trajectory and quantum dual string theoryArtigo10.1016/0370-2693(94)90303-4Acesso restrito2-s2.0-0011444505
