Experimental limits on the lowest possible mass horizontal gauge boson in SU(2) H

A unified picture of both soft and hard hadronic collisions is suggested. The basis idea is to use Regge trajectories of the type $$\alpha (t) = \alpha (0) - \gamma ln (1 + \beta \sqrt {t_0 - t} )$$ in dual models with Mandelstam analyticity. The idea is applied to elastic proton-proton scattering to derive kinematical boundaries of the asymptotic (Regge-t _R and scaling-S _sc.,t _sc.) regimes, to fix the angular dependence in the scaling-and thet-dependence in the Regge domain of the scattering amplitude and to interpolate between the two asymptotic domains.
