Sensitivities on dark photon from the forward physics experiments
Journal 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

Displaced searches for light vector bosons at Belle II
Journal 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
Journal 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.

Journal 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.

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

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

Terrestrial detection of hidden vectors produced by solar nuclear reactions
Journal of High Energy Physics, 2023 Solar nuclear reactions can occasionally produce sub-MeV elusive beyond the Standard Model particles that escape the solar interior without further interactions. This study focuses on massive spin-one particles.

On (g − 2) μ from gauged U(1) X
Journal 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.
