abstract
We argue that a measurement of the Higgs boson self-coupling becomes particularly meaningful in a large and important class of theories when its sensitivity is within 40\% of its Standard Model value. This constitutes a target for a future impactful experimental achievement. It is derived from recently obtained results of how extreme the differences can be between effective field theory operator coefficients when their origins are from reasonable custodial-violating theories beyond the Standard Model.

Triple Higgs Boson Production with Two Heavy Scalars at the LHC via a Simplified Approach
Double-resonant triple Higgs boson production at the LHC can be described by a single rescaling factor rho2, and projected 95% CL limits on rho2 over the (m2,m3) plane make the analysis applicable to any two-narrow-scalar model.
