Precision SMEFT bounds from the VBF Higgs at high transverse momentum

Araz, Jack Y. and Banerjee, Shankha and Gupta, Rick S. and Spannowsky, Michael (2021) 'Precision SMEFT bounds from the VBF Higgs at high transverse momentum.', Journal of High Energy Physics, 2021 (4). p. 125.


We study the production of Higgs bosons at high transverse momenta via vector-boson fusion (VBF) in the Standard Model Effective Field Theory (SMEFT). We find that contributions from four independent operator combinations dominate in this limit. These are the same ‘high energy primaries’ that control high energy diboson processes, including Higgs-strahlung. We perform detailed collider simulations for the diphoton decay mode of the Higgs boson as well as the three final states arising from the ditau channel. Using the quadratic growth of the SMEFT contributions relative to the Standard Model (SM) contribution, we project very stringent bounds on these operators that far surpass the corresponding bounds from the LEP experiment.
