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.

Higgsophilic gauge bosons and monojets at the LHC [PDF]
Journal of High Energy Physics, 2015 We consider a generic framework where the Standard Model (SM) coexists with a hidden sector endowed with some additional gauge symmetry. When this symmetry is broken by a scalar field charged under the hidden gauge group, the corresponding scalar boson generally mixes with the SM Higgs boson.

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 ...

Multi-Boson Interactions at the LHC
, 2016 This review covers results on the production of all possible electroweak boson pairs and 2-to-1 vector boson fusion at the CERN Large Hadron Collider (LHC) in proton-proton collisions at a center of mass energy of 7 and 8 TeV. The data were taken between

NLO+NLL limits on W′ and Z′ gauge boson masses in general extensions of the Standard Model [PDF]
, 2014 A bstractQCD resummation predictions for the production of charged (W′) and neutral (Z′) heavy gauge bosons decaying leptonically are presented. The results of our resummation code at next-to-leading order and next-to-leading logarithmic (NLO+NLL ...

Higgs Mechanism in String Theory [PDF]
Phys.Rev. D56 (1997) 2317-2322, 1997 In first-quantized string theory, spacetime symmetries are described by inner automorphisms of the underlying conformal field theory. In this paper we use this approach to illustrate the Higgs effect in string theory. We consider string propagation on M^{24,1} \times S^1, where the circle has radius R, and study SU(2) symmetry breaking as R moves away ...

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 ...

Gauge boson couplings at LEP [PDF]
Nuclear Physics B - Proceedings Supplements, 2005 A review is given of the measurements of triple and quartic couplings among the electroweak gauge bosons performed at LEP by the four experiments ALEPH, DELPHI, L3 and OPAL. Emphasis is placed on recently published results and on combinations of results performed by the LEP electroweak gauge-couplings group.

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.

Weak gauge boson radiation in parton showers [PDF]
, 2014 A bstractThe emission of W and Z gauge bosons off quarks is included in a traditional QCD + QED shower. The unitarity of the shower algorithm links the real radiation of the weak gauge bosons to the negative weak virtual corrections. The shower evolution
