Abstract (data abstract)
A search for Higgs boson pair (HH) production in association with a vector boson V (W or Z boson) is presented.The search is based on proton-proton (pp) collision data at a center-of-mass energy of 13 TeV,collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $138 fb^{-1}$.The processes in this search include $pp \rightarrow ZHH$ and $pp \rightarrow WHH$ production. All hadronic decaysand leptonic decays of V bosons involving electrons, muons, and neutrinos are considered.Pairs of Higgs bosons are searched for in the $b\bar{b}b\bar{b}$ decay channel.An observed (expected) upper limit at 95\% confidence level of VHH production cross section is set at 294 (124) times the standard model prediction.Constraints are also set on the modifiers of the Higgs boson trilinear self-coupling, $\kappa_{\lambda}$, assuming $\kappa_{2V} = 1$ (SM)and vice versa on the coupling of two Higgsbosons with two vector bosons, $\kappa_{2V}$. The observed (expected) 95\% confidence intervals of these coupling modifiersare $-37.7<\kappa_{\lambda}<37.2$ ($-30.1<\kappa_{\lambda}<28.9$) and $-12.2<\kappa_{2V}<13.5$ ($-7.2<\kappa_{2V}<8.9$), respectively.
