Regge trajectories in the developed model are non-linear for small masses and the values of spin and have the different asymptotical slopes $α_p$. The value $α_p$ just as the form of the trajectory depends from the quantum state of some ''internal'' {relativistic invariant} variables. It is also shown that some trajectories have the asymptotical slope $α_g$=0.21 $Gev^{-2}$.20 pagesHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
