Effective Field Theory Analysis of the Measurement of the Triple Higgs Coupling

An important target of future high-energy collider experiments is the measurement of the triple Higgs boson coupling, which will give us the first information on the shape of the Higgs potential.   Typically, the strategy for extracting this coupling involves measuring the cross section for a double Higgs boson production process.  However, there are many possible effects from beyond the Standard Model that affect the value of double Higgs production cross sections, and it is not obvious that a value of the cross section can be interpreted unambiguously in terms of a shift of the Higgs potential from its Standard Model form.  In this talk, I will explain how to resolve this ambiguity at e+e- colliders, using results from other measurements available there.
