The analysis targets Lorentz-boosted $H$ pairs identified using a graph neural network. It constrains the strengths relative to the standard model of the $H$ self-coupling and the quartic $VVHH$ couplings, $\\kappa_{2V}$, excluding $\\kappa_{2V} = 0$ for the first time, with a significance of 6.3 standard deviations when other $H$ couplings are fixed to their standard model values.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.128973.v1/t1","@type":"Dataset","description":"The data and fitted signal and background distributions for the
