On Lorentz-invariant 2D equations admitting long-lived localized solutions with a nontrivial structure
Abstract
The article studies Lorentz-invariant 2D equations with long-lived (t 1000 ) localized solutions. In the case of three scalar fields localized solutions with a nontrivial internal structure similar to the hadron structure are showed. In this case, the solutions of the equations are analogous to the confinement model by flux tube.
