                      cross sections in proton–proton collisions at
                      center-of-mass energies of 7 and 8 $~\mathrm{TeV}$ are
                      presented. Candidate events for the leptonic decay mode
                      $\mathrm{Z}\mathrm{Z}\rightarrow 2\mathrm{l} 2\nu $ , where
                      $\mathrm{l}$ denotes an electron or a muon, are
                      reconstructed and selected from data corresponding to an
                      integrated luminosity of 5.1 (19.6) $\,\text {fb}^\text
                      {-1}$ at 7 (8) $~\mathrm{TeV}$ collected with the CMS

                      agreement with the standard model predictions with
                      next-to-leading-order accuracy. The selected data are
                      analyzed to search for anomalous triple gauge couplings
                      involving the $\mathrm{Z}$ $\mathrm{Z}$ final state. In the
                      absence of any deviation from the standard model
                      predictions, limits are set on the relevant parameters.
                      These limits are then combined with the previously published
                      CMS results for $\mathrm{Z}$ $\mathrm{Z}$ in 4 $\mathrm{l}$
                      final states, yielding the most stringent constraints on the
                      anomalous couplings.},
