The discovery of a Higgs boson at the Large Hadron Collider motivates searches for physics beyond the Standard Model in channels involving coupling to the Higgs boson.
A search for massive resonances decaying into couples of bosons is described.
The considered final states are: $HH$, $VH$, $VV$, $V\gamma$ and $\gamma\gamma$ with $V$ indicating either the $W$ or the $Z$ boson.
Final states with different number of leptons or photons and where, in many cases, at least one Higgs decays into a b-quark pair are studied using different jet reconstruction techniques which allow to optimize the signal acceptance for low or high Higgs boson transverse momentum.
The most recent diboson resonance searches using LHC Run 2 data are described.
