Description
Assuming the presence of physics beyond the Standard Model
with a characteristic scale $M \sim O(10 ~ TeV)$, we investigate the
naturalness of the Higgs sector at scales below $M$
using an effective field theory (EFT) approach.
We obtain the leading 1-loop EFT
contributions to the Higgs mass with a Wilsonian-like hard cutoff,
and determine the constraints on the corresponding operator coefficients for
these effects to alleviate the ***little hierarchy problem***
up to the scale of the effective action $ \Lambda < M $; a condition we denote
by ***``EFT-naturalness''***.
We also discuss the types of physics that can lead to ***EFT-naturalness*** and
obtain the current experimental constraints on the relevant
operator coefficients; it is shown that these types of new physics
are best probed in vector-boson and multiple-Higgs production.
