Abstract
Within the non-Abelian SU(2) Proca-Higgs theory, we study localized axially symmetric solutions possessing a finite field energy. It is shown that in a certain sense such solutions are analogs of the Nielsen-Olesen tube, since they have a longitudinal magnetic field creating a flux of this field over the central cross section of the Proca tube. The main difference between the Proca tube and the Nielsen-Olesen tube is that the Proca tube is described by a topologically trivial solution and has finite size, since its energy density decreases exponentially with distance. The dependence of the total field mass of the Proca tube on the value of one of the parameters determining the solution is examined in detail. The solutions are obtained both in the presence and in the absence of external sources (charge and current densities).
