We report on studies of the e+e− → HZ process with the subsequent decay of the Higgs boson H → ZZ, where the ZZ combination is reconstructed in the final states with two jets and two leptons. The analysis is performed using Monte Carlo data samples obtained with detailed ILD detector simulation assuming the integrated luminosity 2 ab−1, the beam polarizations Pe−e+ = (−0.8,+0.3), and the center-of-mass energy √ s = 250 GeV. The analysis is also repeated for the case of two 0.9 ab−1 data samples…
