Query: Fixed point scenario in the Two Higgs Doublet Model inspired by
  degenerate vacua   We consider the renormalisation group flow of Higgs and Yukawa couplings
within the simplest non--supersymmetric two Higgs doublet extension of the
Standard Model (SM). In this model the couplings are adjusted so that the
multiple point principle (MPP) assumption, which implies the existence of a
large set of degenerate vacua at some high energy scale $\Lambda$, is realised.
When the top quark Yukawa coupling at the scale $\Lambda$ is large, the
solutions of RG equations in this MPP inspired 2 Higgs Doublet Model (2HDM)
converge to quasi--fixed points. We analyse the Higgs spectrum and couplings in
the quasi--fixed point scenario and compute a theoretical upper bound on the
lightest Higgs boson mass. When the scale $\Lambda$ is low, the coupling of the
SM--like Higgs scalar to the top quark can be significantly larger in the
considered model than in the SM, resulting in the enhanced production of Higgs
bosons at the LHC.
