Multi-Higgs production from a theory of varying Higgs quartic and top Yukawa couplings

We study the collider phenomenology of a theory in which the Higgs quartic self-coupling and the top Yukawa coupling are \textit{varying couplings}, which arise dynamically from two scalar fields, $\phi_1$ and $\phi_2$. Depending on the scalar masses relative to twice the top-quark mass, the heavy scalars decay mainly...
