The Multiple Point Principle and Extended Higgs Sectors
John McDowall, David J Miller
The Higgs boson quartic self-coupling in the Standard Model appears to become zero just below the Planck scale, with interesting implications to the stability fo the Higgs vacuum a…

High Scale Boundary Conditions in Models with Two Higgs Doublets
John McDowall, David J Miller
We investigate high scale boundary conditions on the quartic Higgs-couplings and their -functions in the Type-II Two Higgs Doublet Model and the Inert Doublet Model. These condi…

High scale boundary conditions with an additional complex singlet
John McDowall, David J. Miller
We investigate Planck scale boundary conditions on Higgs quartic interactions and their -functions in the SM augmented by an additional complex scalar. We use renormalisation gr…
