Abstract

In the framework of the dispersion relation technique the relativistic six-quark equations for the molecule Σ_b Σ_b^* are found. The relativistic six-quark amplitudes of the hexaquark including the quarks of three flavors (u, d, b) are calculated. The pole of these amplitudes determines the mass of Σ_b Σ_b^* state M=11620 MeV. The binding energy is equal to 27 MeV.
