Description
We briefly motivate the linear (SMEFT) and non-linear (HEFT) bottom-up EFT extensions of the Standard Model and demonstrate the difference in organizing the theory for the example of Higgs boson pair production at NLO QCD. Comparing $m_{hh}$ distributions for HEFT and SMEFT for different truncation options of dimension 6 operator contributions, we point out to the pitfalls of a naive translation between the two EFTs.
