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.

The ultraviolet landscape of two-Higgs doublet models

TL;DR: In this paper, the authors study the relation between the mass splitting of the heavy Higgs states and the size of the quartic couplings at the matching scale, finding that only a small class of models exhibit sizeable mass splittings between the heavy scalars at the weak scale.

Leptophilic bosons and muon g-2 at lepton colliders

TL;DR: In this article, a light leptophilic boson (scalar or pseudoscalar) has been postulated to explain the muon g-2 anomaly and could be a portal to dark matter, but it is shown that such a hypothetical particle will be unambiguously ruled out or discovered via the Yukawa process at a lepton collider designed as a Higgs factory.

LHC Search of New Higgs Boson via Resonant Di-Higgs Production with Decays into 4W

TL;DR: In this article, the resonant production of a CP-even heavy Higgs state in the di-Higgs channel via, $gg\to H^0\to h^0h^0to WW^*WW^*), at the LHC Run-2 and the high luminosity LHC (HL-LHC), was studied.

EFT diagrammatica: UV roots of the CP-conserving SMEFT

TL;DR: In this article, the authors proposed a diagrammatic approach to establish selection criteria for the allowed heavy field representations corresponding to each effective field theory (SMEFT) operator, and elucidated the links of a chain connecting specific CP conserving dimension-6 SMEFT operators with unique sets of heavy field representation.

CDF $W$ boson mass and muon $g-2$ in type-X two-Higgs-doublet model with a Higgs-phobic light pseudoscalar

TL;DR: In this paper , a comparative study of the Higgs-phobic type-X with and without the CDF m W measurement was performed, and the authors proposed the 4 τ + V V (cid:48) states as the golden discovery channel at the LHC.

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.
