Abstract

One correction is noted for the paper. A wrong cross-section was used for the theory prediction in figure 6 due to not taking into account the VHH contamination properly in the rescaling formula for the signal samples. The change in the theory prediction leads to stricter exclusion limits on the di-vector-boson-di-Higgs-boson coupling modifier κ2V . The observed excluded region corresponds to κ2V < −0.43 and κ2V > 2.56, while the expected exclusion is κ2V < −0.55 and κ2V > 2.72.
