Constraining four-heavy-quark operators with top-quark, Higgs, and electroweak precision data
Stefano Di Noi, Hesham El Faham, Ramona Gröber +2
We establish constraints on the dimension-six four-heavy-quark operators in the Standard Model Effective Field Theory (SMEFT) by synthesising LHC measurements of top-quark and sing…
Two-loop BSM contributions to Higgs pair production in the aligned THDM
Giuseppe Degrassi, Ramona Gröber, Pietro Slavich
We study the impact of the two-loop corrections controlled by the BSM Higgs couplings on the cross section for the production of a pair of SM-like Higgs bosons via gluon fusion in…
: updated predictions at NLO QCD
Benjamin Campillo Aveleira, Long Chen, Joshua Davies +9
We present state-of-the-art predictions for the inclusive cross section of gluon-initiated production, following the recommendations of the LHC Higgs Working Group. In particu…
Two-loop running effects in Higgs physics in Standard Model Effective Field Theory
Stefano Di Noi, Ramona Gröber, Manoj K. Mandal
We consider the renormalization group equations within the Standard Model Effective Field Theory and compute two-loop contributions proportional to the top quark Yukawa coupling fo…
Effective Field Theory descriptions of Higgs boson pair production
Lina Alasfar, Luca Cadamuro, Christina Dimitriadi +9
Higgs boson pair production is traditionally considered to be of particular interest for a measurement of the trilinear Higgs self-coupling. Yet it can offer insights into other co…
