Sensitivities on dark photon from the forward physics experiments

open access: yesJournal of High Energy Physics, 2022
Neutrino-electron scattering experiments can explore the potential presence of a light gauge boson A′ which arises from an additional U(1) B−L group, or a dark photon A′ which arises from a dark sector and has kinetic mixing with the SM hypercharge gauge

Measuring the anomalous quartic gauge couplings in the W + W − → W + W − process at muon collider using artificial neural networks

open access: yesJournal of High Energy Physics, 2022
The muon collider provides a unique opportunity to study the vector boson scattering processes and dimension-8 operators contributing to anomalous quartic gauge couplings (aQGCs).

Displaced searches for light vector bosons at Belle II

open access: yesJournal of High Energy Physics, 2022
With a design luminosity of 50 ab −1 and detectors with tracking capabilities extending beyond 1 m, the Belle II experiment is the perfect laboratory for the search of particles that couple weakly to the Standard Model and have a characteristic decay ...

Resolving the muon g − 2 tension through Z′-induced modifications to σ had

open access: yesJournal of High Energy Physics, 2023
The QED hadronic vacuum polarization function plays an important role in the determination of precision electroweak observables and of the anomalous magnetic moment of the muon.

New chiral fermions, a new gauge interaction, Dirac neutrinos, and dark matter [PDF]

open access: yesJournal of High Energy Physics, 2015
We propose that all light fermionic degrees of freedom, including the Standard Model (SM) fermions and all possible light beyond-the-standard-model fields, are chiral with respect to some spontaneously broken abelian gauge symmetry. Hypercharge, for example, plays this role for the SM fermions.

Axial vectors in DarkCast

open access: yesJournal of High Energy Physics, 2022
In this work, we explore new spin-1 states with axial couplings to the standard model fermions. We develop a data-driven method to estimate their hadronic decay rates based on data from τ decays and using SU(3)flavor symmetry.

Radiative interactions between new non-Abelian gauge sector and the standard model

open access: yesPhysics Letters B, 2021
We discuss one loop generation of the term connecting gauge fields from a local hidden $SU(2)_H$ and the standard model $U(1)_Y$ introducing an $SU(2)_H$ doublet fermion with non-zero hypercharge and a scalar field in adjoint representation. Then we obtain a kinetic mixing term between $SU(2)_H$ and $U(1)_Y$ gauge fields after the adjoint scalar field ...

On (g − 2) μ from gauged U(1) X

open access: yesJournal of High Energy Physics, 2022
We investigate an economical explanation for the (g − 2) μ anomaly with a neutral vector boson from a spontaneously broken U(1) X gauge symmetry. The Standard Model fermion content is minimally extended by 3 right-handed neutrinos.

New constraint on dark photon at T2K off-axis near detector

open access: yesJournal of High Energy Physics, 2023
The T2K experiment is one of the most powerful long-baseline experiments to investigate neutrino oscillations. The off-axis near detector called ND280 is installed 280 m downstream from the neutrino production target to measure the neutrino energy ...
