Higgs boson pair production in SMEFT: shape and truncation studies
Manosch Bär, Bakar Chargeishvili, Ramona Gröber +2
We present a comparative study of the influence of Wilson coefficients on Higgs boson pair production cross sections in SMEFT up to dimension-6, also including loop-suppressed oper…

Higgs pair production in gluon fusion to higher orders in Higgs Effective Field Theory
Ilaria Brivio, Ramona Gröber, Konstantin Schmid
Higgs pair production offers the opportunity to probe correlations among the couplings of one or two Higgs bosons to fermions and gauge bosons. In this context, it serves as a powe…

The Art of Counting: a reappraisal of the HEFT expansion
Ilaria Brivio, Ramona Gröber, Konstantin Schmid
We revisit the power counting of the Higgs Effective Field Theory (HEFT) from first principles, by requiring that predictions for physical observables follow a series expansion in…
