Precise predictions for boosted Higgs production - Becker, Kathrin et al - arXiv:2005.07762CERN-TH-2020-074
 
Transverse momentum distribution of the Higgs boson at the LHC with $\sqrt{s}=13$~TeV computed in refs.~\cite{Chen:2016zka,Jones:2018hbb}. The upper panel shows absolute predictions at LO (${\cal O}(\alpha_s^3)$) and NLO (${\cal O}(\alpha_s^4)$) in the full SM and in the infinite $\mtop$ approximation (EFT), as well as the NNLO (${\cal O}(\alpha_s^5)$) in the EFT. The lower panels show the ratio of the EFT and full SM predictions to their respective LO calculations. The bands indicate theoretical errors obtained with a 7-point scale variation.

The lower panels show the ratio of the EFT and full SM predictions to their respective LO calculations. The bands indicate theoretical errors obtained with a 7-point scale variation, i.e. we perform a variation of $\mu_R$ and $\mu_F$ by a factor of two around their central value by keeping $ 1/2\leq \mu_R/\mu_F \leq 2$.
Cumulative cross section as a function of the $p_\perp$ cut at NNLO in the heavy-top EFT, as well as rescaled by the LO (NLO) full-SM spectrum labelled by EFT-improved$(0)$ (EFT-improved$(1)$). See the text for description. The ratio of the EFT-improved$(1)$ and EFT-improved$(0)$ predictions is shown in Fig.~\ref{fig:relativefinal}
Ratio of the cumulative cross section as defined in the EFT-improved$(0)$ and EFT-improved$(1)$ approximation (see the text for description) to the central value of the EFT-improved$(1)$ result as a function of the $p_\perp$ cut.
Cumulative cross section for the production of a Higgs boson as a function of the Higgs boson transverse momentum cut. The cross section due to the gluon-fusion (green), VBF (red), vector boson associated (blue) and top-quark pair associated (magenta) production mode are shown in absolute values (left) and relative size (right).
