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.

Self-cancellation of a scalar in neutral meson mixing and implications for the LHC

Miguel Nebot, +1 more
- 28 Jul 2015 - 
TL;DR: In particular, when the spin 0 particle has both scalar and pseudoscalar couplings, one may have a self-cancellation as discussed by the authors, and the flavour changing quark interactions can lead to new production mechanisms for a neutral scalar at LHC.

Heavy stable charged tracks as signatures of non-thermal dark matter at the LHC: a study in some non-supersymmetric scenarios

TL;DR: In this article, the authors considered two theoretical scenarios, each including a ℤ2-odd sector and leading to an elementary dark matter candidate, and they considered two kinds of signals at the Large Hadron Collider for each case.

Muon g - 2 and Galactic Centre γ-ray excess in a scalar extension of the 2HDM type-X

TL;DR: In this paper, an extension of the lepto-specific 2HDM with an extra singlet S as a dark matter candidate is considered, and the authors investigate the possibility to address both the γ-ray excess detected at the Galactic Centre and the discrepancy between the Standard Model prediction and experimental results of the anomalous magnetic moment of the muon.

Collider bounds on 2-Higgs doublet models with U(1) X gauge symmetries

TL;DR: In this paper, the authors derived updated collider bounds on the Z-gauge boson generated by the spontaneous breaking of the Abelian group U ( 1 ) X and employed the corresponding datasets as obtained at the Large Hadron Collider (LHC) at the 13 TeV CMs energy for L = 12, 36 and 300 fb−1 of luminosity.

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.
