Gauge transformations of spin-orbit interactions in graphene [PDF]
, 2015 Inclusion of spin-dependent interactions in graphene in the vicinity of the Dirac points can be posed in terms of non-Abelian gauge potentials. Such gauge potentials being surrogates of physical electric fields and material parameters, only enjoy a ...

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.

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.

New Gauge Interactions and Single Top Quark Production [PDF]
, 1996 Extensions of the standard model that include new W bosons or extended technicolor gauge bosons can predict sizeable changes in the rate of single top quark production, even when constrained to be consistent with precision electroweak data.

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

Probing new light gauge bosons with gravitational-wave interferometers using an adapted semicoherent method [PDF]
Physical Review D, 2020 We adapt a method, originally developed for searches for quasi-monochromatic, quasi-infinite gravitational-wave signals, to directly detect new light gauge bosons with laser interferometers, which could be candidates for dark matter.

Flavor non-universal gauge interactions and anomalies in B-meson decays [PDF]
, 2017 Motivated by flavor non-universality and anomalies in semi-leptonic B-meson decays, we present a general and systematic discussion about how to construct anomaly-free $U(1)'$ gauge theories based on an extended standard model with only three right-handed

Gauge invariant double copy of Yang-Mills theory: The quartic theory [PDF]
Physical Review D, 2022 We give an explicit gauge invariant, off-shell and local double copy construction of gravity from Yang-Mills theory to quartic order. To this end we use the framework of homotopy algebras, and we identify a rich new algebraic structure associated to ...

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.
