Description
In this investigation we study the most general two Higgs doublet model with
SU(2) gauge fields on the lattice.
The phase space is probed through the computation of gauge-invariant global
observables serving as proxies for order parameters.
In each phase, the spectrum of the theory is analysed for different combinations
of bare couplings and different symmetry breaking patterns.
The scale setting and calculation of the gauge running coupling are done through
the Wilson flow computation of the action density.
The computation of the renormalised gauge coupling for the Higgs theory is first
tested in a single doublet model for various values of the cutoff on a line of
constant physics within the Higgs phase of the theory.
