BSM effects on the Higgs transverse-momentum spectrum in an EFT approach
Abstract
Effective Field Theories offer a consistent bottom-up approach to parametrise small deviations from Standard Model predictions. In this work we report on the application of the Effective Field Theory to shed light on effects from high-scale physics beyond the Standard Model on the Higgs transverse-momentum spectrum. The Standard Model prediction for the transverse-momentum distribution in Higgs boson production through gluon fusion is augmented by three new dimension-six operators, implying the modification of the top and bottom Yukawa couplings, and the inclusion of a point-like Higgs-gluon coupling. We present resummed transverse-momentum spectra including these operators at NLO+NLL accuracy and study their effects on the shape of the distribution. The proper parametrization of such effects becomes increasingly important for experimental analyses in Run II of the LHC.
