Sensitivity to BSM effects in the Higgs p T spectrum within SMEFT

Abstract The study of Higgs boson production at large transverse momentum is one of the new frontiers for the LHC Higgs physics programme. This paper considers boosted Higgs production in the Standard Model Effective Field Theory (SMEFT). We focus on the gluon fusion and t t ¯ $$ \overline{t} $$ H p...
