Constraints on the quartic Higgs self-coupling from double-Higgs production at future hadron colliders

Abstract We study the indirect constraints on the quartic Higgs self-coupling that arise from double-Higgs production at future hadron colliders. To this purpose, we calculate the two-loop contributions to the gg → hh amplitudes that involve a modified h 4 vertex. Based on our results, we estimate t...
