We here report on the progress of HHH Workshop, that took place in Dubrovnik July 2023. After discovery a particle complies with properties Higgs boson Standard Model, all SM parameters are principle determined. However, order to verify or falsify model, full form potential has be This includes measurement triple and quartic scalar couplings. ongoing measurements for multi final states, an emphasis three SM-like bosons at 125 GeV, but also mentioning other options. discuss both experimental challenges as well theoretical studies models can enhance such rates respect predictions.
