In this article, the authors studied the process of reconstructing the Higgs boson at high energies using subjet techniques using the standard model effective field theory (SMEFT).Abstract:
We study the process pp → Zðlþl−Þhðbb¯Þ in the standard model effective field theory (SMEFT) at
high energies using subjet techniques to reconstruct the Higgs boson. We show that at high energies this
process probes four directions in the dimension-6 EFT space, namely the operators that contribute to the
four contact interactions, hZμf¯ γμf, where f ¼ uL; uR; dL and dR. These four directions are, however,
already constrained by the Z-pole and diboson measurements at LEP. We show that by utilizing the energy
growth of this process in the SMEFT and the accuracy that can be achieved by using subjet techniques at the
High Luminosity LHC, one can obtain bounds on these operators that are an order of magnitude better than
existing LEP bounds.read more

On the impact of dimension-eight SMEFT operators on Higgs measurements
TL;DR: In this article, the effect of dimension-8-SM interference and dimension-6-squared terms appeared at the same order in an expansion in 1/Λ, and the authors showed that the effect on the inferred new physics scale is small, with some variation depending on the relative signs of the dimension8 coefficients.
Journal ArticleDOI
Diboson at the LHC vs LEP
TL;DR: In this paper, the authors use the current CMS and ATLAS data for the leptonic pp → WW, WZ channels to show that diboson production is, for a broad class of flavour models, already competitive with LEP-1 measurements for setting bounds on the anomalous couplings between the quarks and the electroweak gauge bosons, at least under the assumption that any new particle is heavier than a few TeV.
