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.

Gauge invariant one-loop corrections to Higgs boson couplings in nonminimal Higgs models [PDF]
, 2017 We comprehensively evaluate renormalized Higgs boson couplings at one-loop level in non-minimal Higgs models such as the Higgs Singlet Model (HSM) and the four types of Two Higgs Doublet Models (THDMs) with a softly-broken $Z_2$ symmetry.

Diphoton channel at the LHC experiments to find a hint for a new heavy gauge boson [PDF]
, 2015 Recently there has been a huge interest in the diphoton excess around 750 GeV reported by both ATLAS and CMS collaborations, although the newest analysis with more statistics does not seem to support the excess.

NLO QCD+EW corrections to diphoton production in association with a vector boson
Journal of High Energy Physics, 2018 Processes with three external electroweak gauge boson allow for a measurement of triple and quartic gauge couplings. They can be used to constrain anomalous gauge couplings, where new physics might predominantly couple to electroweak gauge bosons.

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.

Multi‐Channel Quantum Dot Single‐Photon Sources on a Fiber‐Integrated Platform
Advanced Optical Materials, EarlyView.A breakthrough in achieving a multiple, tunable array of quantum photonic devices is presented. By combining an optimal nanophotonic cavity, individual device transfer process, and integrated electrodes on a V‐groove fiber, the all‐fiber integrated system exhibits capabilities of low‐temperature cooling, efficient single‐photon transmission, selective ...

Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts
Advanced Science, EarlyView.The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Muon g-2 Anomaly and Dark Leptonic Gauge Boson [PDF]
, 2014 One of the major motivations to search for a dark gauge boson of MeV-GeV scale is the long-standing muon g-2 anomaly. Because of active searches such as fixed target experiments and rare meson decays, the muon g-2 favored parameter region has been ...

The SU(2)$_{D}$ lepton portals for muon g - 2, W boson mass and dark matter
SciPost Physics Proceedings, 2023 We propose a novel model which extends the Standard Model (SM) by introducing a $SU(2)_D$ gauge symmetry. In this model, a dark $SU(2)_D$ Higgs doublet and a Higgs bi-doublet can contribute to the muon g-2 anomaly and the $W$ boson mass, remaining in ...
