In this paper, a simple and straightforward way of constraining the W′ mass directly from the decay of the Higgs boson to two photons is proposed, which is applicable to a diverse range of models with a W′-boson that couples to the Standard Model-like Higgs particle.Abstract:
Using the left-right symmetric model as an illustrative example, we suggest a simple and straightforward way of constraining the W′ mass directly from the decay of the Higgs boson to two photons. The proposed method is generic and applicable to a diverse range of models with a W′-boson that couples to the Standard Model-like Higgs boson. Our analysis exemplifies how the precision measurement of the Higgs to diphoton signal strength can have a pivotal role in probing the scale of new physics.read more

Neutral Higgs boson decays H →Z γ ,γ γ in 3-3-1 models
TL;DR: Okada et al. as discussed by the authors showed that the Higgs sector becomes effectively the same as that in the two Higgs doublet models (2HDM) after the first symmetry breaking from $SU(3{)}_{L}$ scale into the electroweak scale.

Constraining the gauge and scalar sectors of the doublet left-right symmetric model
TL;DR: In this paper, the authors consider a left-right symmetric extension of the Standard Model where the spontaneous breakdown of the left right symmetry is triggered by doublets and show that the fit pushes the scale of symmetry breaking up to a few TeV, while favouring an electroweak symmetry breaking triggered not only by SU(2)L × SU( 2)R bi-doublet, but also by the SU(1)L doublet.

Lepton Number as the Fourth Color
TL;DR: In this paper, a non-Abelian renormalizable anomaly-free subgroup of the fundamental symmetry structure is defined, which unites three quartets of colored baryonic quarks and the quartet of known leptons into 16-folds of chiral fermionic multiplets, with lepton number treated as the fourth color quantum number.

Exact left-right symmetry and spontaneous violation of parity
TL;DR: In this article, it was shown that maximal parity violation in low-energy weak processes arises purely as a result of spontaneous breakdown of the local gauge symmetry, and the question of dynamical origin of parity violation was discussed.
