Vector boson dark matter from trinification
Journal of High Energy Physics, 2022 We show how trinification models based on the gauge group SU(3) C × SU(3) L × SU(3) R realized near the TeV scale can provide naturally a variety of dark matter (DM) candidates.

Self-couplings of gauge bosons in 3-3-1 models
Tạp chí Khoa học, 2023 In this work, we will present detailed calculations to derive the exact formulas of the triple and quartic self-couplings of all gauge bosons predicted by the general 3-3-1 model with an arbitrary parameter β used to classify different 3-3-1 models.

Impact of the PDFs on the Z and W lineshapes at LHC
European Physical Journal C: Particles and Fields, 2020 The parton distribution functions (PDFs) of the proton play a role in determining the lineshape of Z and W bosons produced at the LHC. In particular, the mode of the gauge boson virtuality is shifted with respect to the pole due to the dependence of the ...

Journal of High Energy Physics, 2018 We construct a self-interacting dark matter model that could simultaneously explain the observed muon anomalous magnetic moment. It is based on a gauged U1Lμ−Lτ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ extension of the standard model, where we ...

General structure of gauge boson propagator and its spectra in a hot magnetized medium
European Physical Journal C: Particles and Fields, 2019 Based on transversality condition of gauge boson self-energy we have systematically constructed the general structure of the gauge boson two-point functions using four linearly independent basis tensors in presence of a nontrivial background i.e.

Helicity amplitudes without gauge cancellation for electroweak processes
European Physical Journal C: Particles and Fields, 2023 In the 5-component representation of weak bosons, the first four components make a Lorentz four vector, representing the transverse and longitudinal polarizations excluding the scalar component of the weak bosons, whereas its fifth component corresponds ...

Once more on the Higgs decay into two photons
Nuclear Physics B, 2018 We comment on the recently reiterated claim that the contribution of the W-boson loop to the Higgs boson decay into two photons leads to different expressions in the Rξ gauge and the unitary gauge.

Gauge Boson Mixing in the 3-3-1 Models with Discrete Symmetries
Advances in High Energy Physics, 2012 The mixing among gauge bosons in the 3-3-1 models with the discrete symmetries is investigated. To get tribimaximal neutrino mixing, we have to introduce sextets containing neutral scalar components with lepton number L=1,2.
