TLDR
In this article, theoretical and phenomenological aspects of two-Higgs-doublet extensions of the Standard Model are discussed and a careful study of spontaneous CP violation is presented, including an analysis of the conditions which have to be satisfied in order for a vacuum to violate CP.

Scalar sector of Two-Higgs-Doublet models: A mini-review

TL;DR: In this paper, the authors review the different parametrizations of the 2Higgs-Doublet potential and discuss the constraints on the parameter space arising from the unitarity and stability of the potential together with constraints from the oblique electroweak $T$-parameter.

Interim recommendations for the evaluation of Higgs production cross sections and branching ratios at the LHC in the Two-Higgs-Doublet Model

TL;DR: In this article, the authors give interim recommendations on how to evaluate LHC cross sections for neutral Higgs production and Higgs branching ratios in the general (CP-conserving) Two-Higgs-Doublet Model (2HDM).

Inflation and dark matter in two Higgs doublet models

TL;DR: In this paper, the authors consider the Higgs inflation in the extension of the Standard Model with two Higgs doublets coupled to gravity non-minimally, and show that the doublet dark matter is always heavy in multi-field inflation while it can be light due to the suppression of the co-annihilation in single field inflation.

Vector boson fusion at multi-TeV muon colliders

TL;DR: In this article, it was shown that starting from collider energies of a few TeV, electroweak (EW) vector boson fusion/scattering at lepton colliders becomes the dominant production mode for all Standard Model processes relevant to studying the EW sector.

Comprehensive study of two Higgs doublet models in light of the new boson with mass around 125 GeV

TL;DR: In this article, a new Higgs doublet was reported, whose signals in various decay modes resemble those of the standard model (SM) Higgs boson, observed are the combinations of entangled information about the production, decay rates and total decay width of the new boson.

CP Conservation in the Presence of Pseudoparticles

TL;DR: In this paper, the authors give an explanation of the conservation of strong interactions which includes the effects of pseudoparticles, and they find it is a natural result for any theory where at least one flavor of fermion acquires its mass through a Yukawa coupling to a scalar field which has nonvanishing vacuum expectation value.

Broken Symmetries and the Masses of Gauge Bosons

TL;DR: In this paper, it was shown that the spin-one quanta of some of the gauge fields acquire mass; the longitudinal degrees of freedom of these particles (which would be absent if their mass were zero) go over into the Goldstone bosons when the coupling tends to zero.

Broken Symmetry and the Mass of Gauge Vector Mesons

TL;DR: In this paper, it was shown that in certain cases vector mesons do indeed acquire mass when the vacuum is degenerate with respect to a compact Lie group, and that strong interaction physics originates from massive gauge fields related to a system of conserved currents.
