The object of research is the processes of elastic and inelastic hadrons scattering. The goal is to build a dynamic model of hadron scattering to describe experimental data. The research method is the Laplace method for calculating the differential cross-section of elastic hadron scattering on the transmitted four-momentum. The paper proposes a model for describing hadron scattering processes as bound states of constituent quarks. On the simultaneity subset, the construction of dynamical equations for multi-particle fields using the Lagrange method is considered, similar to how it is done for "normal" single-particle fields. The gauge fields that restore the local internal symmetry on the simultaneity subset are considered. For multiparticle fields that describe mesons as bound quark and antiquark states and are two-index tensors relative to the local gauge group, a model with two different gauge fields, each of which is associated with its index, is proposed. Such fields are transformed according to the same law in the local gauge transformation and satisfy the same dynamic equation, but different boundary conditions are imposed on them. Under certain boundary conditions, these equations describe such physical phenomena as confinement and asymptotic freedom of colored objects, and under other boundary conditions - the mechanism of spontaneous symmetry breaking. These dynamic equations make it possible to describe both the containment of quarks inside hadrons and their interaction in the processes of hadron scattering, through the exchange of bound states of gluons - globules, within the same model.
