Аннотация: We calculated the shear viscosity of hot and dense nuclear matter produced in a symmetricsystem of central gold–gold collisions at energies of BES RHIC, FAIR and NICA. For calculations ofthe collisions, the transport model UrQMD was employed. The shear viscosity was obtained withinthe Green–Kubo formalism. The hadron resonance gas model was used to determine temperatureand chemical potentials of baryon charge and strangeness out of microscopic model calculations. Incontrast to our previous works, we determined the partial viscosity of the main hadron species, suchas nucleons, pions, kaons and Lambdas, via the nucleon–nucleon, pion–pion and so forth, correlators.A decrease in the beam energy from Elab = 40 to 10 AGeV leads a to rise in baryon shear viscosityaccompanied by a drop in the shear viscosity of mesons. The ratio of total shear viscosity to entropydensity also decreases.
