Modeling BSM effects on the Higgs transverse-momentum spectrum in an EFT approach

Understand

We consider the transverse-momentum distribution of a Higgs boson produced through gluon fusion in hadron collisions.

• At small transverse momenta, the large logarithmic terms are resummed up to next-to-leading-logarithmic (NLL) accuracy.
• The resummed computation is consistently matched to the next-to-leading-order (NLO) result valid at large transverse momenta.
• The ensuing Standard Model prediction is supplemented by possible new-physics effects parametrised through three dimension-six operators related to the modification of the top and bottom Yukawa couplings, and to the inclusion of a point-like Higgs-gluon coupling, respectively.
