On the possibility of a search for the $L_\mu - L_\tau$ gauge boson at Belle-II and neutrino beam experiments [PDF]

open access: yes, 2016
We study the possibilities on the search of the light and weakly interacting gauge boson in the gauged $L_\mu - L_\tau$ model. Introducing the kinetic mixing at the tree-level, the allowed parameter regions for the gauge coupling and kinetic mixing ...

The Higgs and leptophobic force at the LHC

open access: yesJournal of High Energy Physics, 2020
The Higgs boson could provide the key to discover new physics at the Large Hadron Collider. We investigate novel decays of the Standard Model (SM) Higgs boson into leptophobic gauge bosons which can be light in agreement with all experimental constraints.

Lμ-Lτ gauge-boson production from lepton flavor violating τ decays at Belle II [PDF]

open access: yes, 2017
$L_\mu -L_\tau$ gauge boson ($Z'$) with a mass in the MeV to GeV region can resolve not only the muon $g-2$ excess, but also the gap in the high-energy cosmic neutrino spectrum at IceCube.

Double-real corrections at $${{\mathcal {O}}(\alpha \alpha _s)}\,$$O(ααs)to single gauge boson production [PDF]

open access: yes, 2016
We consider the $${{\mathcal {O}}(\alpha \alpha _s)}\,$$O(ααs)corrections to single on-shell gauge boson production at hadron colliders. We concentrate on the contribution of all the subprocesses where the gauge boson is accompanied by the emission of ...

W boson mass tension caused by its right-handed gauge coupling at high energies?

open access: yesNuclear Physics B, 2022
The CDF collaboration's recent high-precision measurement of the W mass is in 7.0σ disagreement with the Standard Model expectation. This tension will be relieved if the W boson has a non-trivial right-handed gauge coupling at high energies.

LHC constraints on gauge boson couplings to dark matter [PDF]

open access: yes, 2015
Collider searches for energetic particles recoiling against missing transverse energy allow to place strong bounds on the interactions between dark matter (DM) and standard model particles.

Mixing particle production for relaxion mechanism

open access: yesJournal of High Energy Physics, 2022
We consider the production of two heavy gauge bosons as a relaxation stopping mechanism. In this work, we analyse the conditions for a tachyonic mode for a linear combination of gauge bosons and show that the criteria are significantly different than the

Constraints on the U(1)L gauge boson in a wide mass range [PDF]

open access: yes, 2015
There is a growing interest for the search of new light gauge bosons. The small mass of a new boson can turn various kinds of low-energy experiments to a new discovery machine, depending on their couplings to the Standard Model particles. It is important

Measurement of VH, H → b b ¯ $$ \mathrm{H}\to \mathrm{b}\overline{\mathrm{b}} $$ production as a function of the vector-boson transverse momentum in 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
Cross-sections of associated production of a Higgs boson decaying into bottomquark pairs and an electroweak gauge boson, W or Z, decaying into leptons are measured as a function of the gauge boson transverse momentum.

Weyl symmetry inspired inflation and dark matter

open access: yesPhysics Letters B, 2020
Motivated by the Weyl scaling gauge symmetry, we present a theoretical framework to explain cosmic inflation and dark matter simultaneously. This symmetry has been resurrected in recent attempts to formulate the gauge theory of gravity.
