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 V V H H couplings, κ 2 V , excluding κ 2 V = 0 for the first time, with a significance of 6.3 standard deviations when other H couplings are fixed to their standard model values. © 2023 CERN, for the CMS Collaboration.American Physical Society2023Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/12103https://doi.org/10.1103/physrevlett.131.0418030031-9007enPhysical Review Lettersinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12103
