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…
Infra-red enhanced loops in quadratic gravity
Alberto Salvio, Alessandro Strumia, Marco Vitti
It has been suggested that logarithmically enhanced infra-red loop corrections arising in theories with four derivatives correspond to a physical running of couplings, rendering qu…
: 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 QCD corrections to and off-shell boson pair production in gluon fusion
Joshua Davies, Dominik Grau, Kay Schönwald +3
We compute two-loop corrections to the associated production of a Higgs boson with a boson and to off-shell boson pair production in the gluon fusion channel, mediated by a…
