Description
We investigate electroweak corrections to gluon-fusion Higgs pair production in Higgs Effective Field Theory, allowing independent variations of the cubic and quartic self-couplings. We determine the complete self-coupling-dependent NLO cross-section coefficients and the NNLO terms quadratic in the quartic coupling. Combining these results with vector-boson-fusion predictions, we examine their impact on cross sections and self-coupling constraints inferred from experimental bounds.
