Sensitivity to BSM effects in the Higgs $p_T$ spectrum within SMEFT

Understand

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 $t{\bar t}H$ production processes and study the effects of three dimension-6 operators: the top Yukawa operator, the gluon-Higgs effective coupling and the chromomagnetic dipole operator of the top quark.
• We perform a detailed study of the sensitivity of current and future LHC data to the corresponding Wilson coefficients, consistently accounting for their renormalisation group evolution.
