DESCRIPTION:We consider extended scalar sectors of the Standard Model as u
ltraviolet–complete motivations for studying the effective Higgs self–
interaction operators of the Standard Model effective field theory. We inv
estigate all motivated heavy scalar models which generate the dimension–
6 effective operator\, |H|^6\, at tree level and proceed to identify the f
ull set of tree–level dimension–six operators by integrating out the h
eavy scalars. Next we perform global fits to constrain relevant Wilson coe
fficients from the LHC single Higgs measurements as well as the electrowea
k oblique parameters S and T. In order to determine the extent to which th
e Wilson coefficient of the |H|^6 operator may be constrained at a future
100 TeV collider we study the di–Higgs process and simulate its signatur
es at the proposed collider. We explore future sensitivity of the Higgs se
lf–interaction operators at the future collider and project it onto the
Higgs potential parameters of the extended scalar sectors to identify the
discovery potentials in future.\n\nhttp://conference.ippp.dur.ac.uk/event/
