Full three-loop renormalisation of an abelian chiral gauge theory with non-anticommuting γ5 in the BMHV scheme [PDF]
Journal of High Energy Physics, 2023 In this work we present a complete three-loop renormalisation of an abelian chiral gauge theory within the Breitenlohner-Maison/’t Hooft-Veltman (BMHV) scheme of dimensional regularisation (DReg).

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 ...

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

Journal 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).

Confinement induced frustration in a one-dimensional Z2 lattice gauge theory [PDF]
New Journal of Physics, 2022 Coupling dynamical charges to gauge fields can result in highly non-local interactions with a linear confining potential. As a consequence, individual particles bind into mesons which, in one dimension, become the new constituents of emergent Luttinger ...

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.

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.
