      abstract     = {The global polarization of ${\Lambda}$ hyperons along the
                      total orbital angular momentum of a relativistic heavy-ion
                      collision is presented based on the high statistics data
                      samples collected in Au+Au collisions at $\sqrt{s_{NN}}$ =
                      2.4 GeV and Ag+Ag at 2.55 GeV with the High-Acceptance
                      Di-Electron Spectrometer (HADES) at GSI, Darmstadt. This is
                      the first measurement below the strangeness production
                      threshold in nucleon-nucleon collisions. Results are
                      reported as a function of the collision centrality as well
                      as a function of the hyperon transverse momentum $(p_T)$ and
                      rapidity $(y_{CM})$ for the range of centrality $0--40\%.$
                      We observe a strong centrality dependence of the
                      polarization with an increasing signal towards peripheral
                      collisions. For mid-central $(20--40\%)$ collisions the
                      polarization magnitudes are $<P_{\Lambda}>(\%)$ = 6.8 $\pm$
                      1.3 (stat.) $\pm$ 2.1 (syst.) for Au+Au and
                      $<P_{\Lambda}>(\%)$ = 6.2 $\pm$ 0.4 (stat.) $\pm$ 0.6
                      (syst.) for Ag+Ag, which are the largest values observed so
                      far. This observation thus provides a continuation of the
                      increasing trend previously observed by STAR and contrasts
                      expectations from recent theoretical calculations predicting
                      a maximum in the region of collision energies about 3 GeV.
                      The observed polarization is of a similar magnitude as
                      predicted by 3D fluid dynamics and the UrQMD plus thermal
                      vorticity model and significantly above results from the
                      AMPT model.},
