Higgs boson production at large transverse momentum within the SMEFT: analytical results

Abstract We consider Higgs boson production through gluon fusion at large transverse momentum in hadronic collisions. We present the analytic expressions of the relevant one-loop QCD amplitudes including the effects of the complete set of dimension-six operators. The latter correspond to modificatio...
