In spite of the non-observation of any new resonances after the discovery of the Standard Model (SM) Higgs-like particle, which announces the success of the SM, we have enough reason to believe the existence of theories beyond it (BSM), with the SM as a part. As any such theory will affect the electroweak and the Higgs sector, and the sensitivity of these precision observables is bound to increase in the near future, indirect estimation of the allowed room left for BSM using Standard Model effective field theory (SMEFT) is well motivated.
