Gravitational positivity for phenomenologists: Dark gauge boson in the swampland [PDF]
Physical Review D, 2023 The gravitational positivity bound gives quantitative “swampland” constraints on low-energy effective theories inside theories of quantum gravity. We give a comprehensive discussion of this bound for those interested in applications to phenomenological ...

Neutrino astronomy as a probe of physics beyond the Standard Model: Decay of sub-MeV B−L gauge boson dark matter [PDF]
Physical Review D, 2022 The $U(1)_{B\textrm{--}L}$ symmetry, the essential component in the seesaw mechanism and leptogenesis, is naturally equipped with a massive gauge boson.

Dark gauge boson emission from supernova pions [PDF]
Physical Review D, 2022 The hot, neutron-rich, and dense circumstance in core-collapse supernovae provides a source of negatively charged pions that may make up a significant portion of the matter.

Anomaly Cancellation with an Extra Gauge Boson. [PDF]
Physical Review Letters, 2020 Many extensions of the standard model include an extra gauge boson, whose couplings to fermions are constrained by the requirement that anomalies cancel.

European Physical Journal C: Particles and Fields, 2021 We consider a model with gauged $$L_\mu ^{} - L_\tau ^{}$$ L μ - L τ symmetry in which the symmetry is spontaneously broken by a scalar field. The decay of the scalar boson into two new gauge bosons is studied as a direct consequence of the spontaneous ...

CDF W mass anomaly with a Stueckelberg-Higgs portal
Physics Letters B, 2022 We propose an explanation to the new W mass measurement recently reported by the CDF collaboration, which is larger than the standard model expectation by about 7 standard deviations.

Journal of High Energy Physics, 2020 Inspired by the Goldstone equivalence gauge, we study the thermal corrections to an originally massive vector boson by checking the poles and branch cuts. We find that part of the Goldstone boson is spewed out from the longitudinal polarization, becoming

Searching for boosted dark matter mediated by a new gauge boson [PDF]
, 2020 We study the possibility to directly detect the boosted dark matter generated from the scatterings with high energetic cosmic particles such as protons and electrons. As a concrete example, we consider the sub-GeV dark matter mediated by a $U(1)_D$ gauge

Structure of Chern-Simons scattering amplitudes from topological equivalence theorem and double-copy
Journal of High Energy Physics, 2022 We study the mechanism of topological mass-generation for 3d Chern-Simons (CS) gauge theories, where the CS term can retain the gauge symmetry and make gauge boson topologically massive.
