Updating neutrino magnetic moment constraints [PDF]

open access: yesPhysics Letters B, 2016
In this paper we provide an updated analysis of the neutrino magnetic moments (NMMs), discussing both the constraints on the magnitudes of the three transition moments Λi and the role of the CP violating phases present both in the mixing matrix and in ...

Tau magnetic moment

open access: yesJournal of Physics: Conference Series, 2017
The τ lepton magnetic moment theoretical predictions and measurements are reviewed. While it is believed that such a high mass particle is a good candidate to show up new physics, this is not the case up to now. The magnetic moment of elementary fermions, and in particular the anomalous magnetic moment of the electron, had an historical impact both in ...

Large Orbital Magnetic Moment in VI3. [PDF]

open access: yesNano Lett, 2023
The existence of the V3+-ion orbital moment is an open issue of the nature of magnetism in the van der Waals ferromagnet VI3. The huge magnetocrystalline anisotropy in conjunction with the significantly reduced ordered magnetic moment compared to the ...

Measurement of the Positive Muon Anomalous Magnetic Moment to 0.20 ppm. [PDF]

open access: yesPhysical Review Letters, 2023
We present a new measurement of the positive muon magnetic anomaly, a_{μ}≡(g_{μ}-2)/2, from the Fermilab Muon g-2 Experiment using data collected in 2019 and 2020.

Measurement of the Electron Magnetic Moment. [PDF]

open access: yesPhysical Review Letters, 2022
The electron magnetic moment, -μ/μ_{B}=g/2=1.001  159 652  180 59 (13) [0.13 ppt], is determined 2.2 times more accurately than the value that stood for fourteen years.

Gate-Tunable Phonon Magnetic Moment in Bilayer Graphene. [PDF]

open access: yesPhysical Review Letters, 2023
We develop a first-principles quantum scheme to calculate the phonon magnetic moment in solids. As a showcase example, we apply our method to study gated bilayer graphene, a material with strong covalent bonds.

Phonon Magnetic Moment from Electronic Topological Magnetization. [PDF]

open access: yesPhysical Review Letters, 2021
The traditional theory of magnetic moments for chiral phonons is based on the picture of the circular motion of the Born effective charge, typically yielding a small fractional value of the nuclear magneton. Here we investigate the adiabatic evolution of

Leading hadronic contribution to the muon magnetic moment from lattice QCD [PDF]

open access: yesNature, 2020
The standard model of particle physics describes the vast majority of experiments and observations involving elementary particles. Any deviation from its predictions would be a sign of new, fundamental physics.

The neutrino magnetic moment portal: cosmology, astrophysics, and direct detection [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left-handed Standard Model neutrinos.
