Standard Model Muon Magnetic Dipole Moment [PDF]

open access: yes, 2023
The most recent high-precision determination of the hadronic leading order contribution to the muon magnetic dipole moment within the Standard Model of particle physics has revealed a five standard deviation discrepancy with the previous determination ...

Li-8 Magnetic Dipole-Moment [PDF]

open access: yes, 1973
Polarized 8Li nuclei recoiling from the reaction 7Li(d, p)8Li were implanted in Au, Pd, and Pt foils, and the Knight-shifted values of the 8Li magnetic dipole moment in these metals were measured by a resonant depolarization technique.

Magnetic field measurements during the ROSETTA flyby at asteroid (21) Lutetia [PDF]

open access: yes, 2011
On July 10, 2010, the ROSETTA spacecraft performed a flyby at asteroid (21) Lutetia at a solar distance of 2.72 AU. The spacecraftâ  asteroid distance at closest approach was 3120 km.

The tau weak-magnetic dipole moment [PDF]

open access: yes, 1994
We calculate the prediction for the anomalous weak-magnetic form factor of the tau lepton at q2=M2Z within the Standard Model. With all particles on-shell, this is a electroweak gauge invariant quantity. Its value is awτ(M2Z)=−(2.10+0.61i)×10−6.

Spin tune mapping as a novel tool to probe the spin dynamics in storage rings

open access: yesPhysical Review Accelerators and Beams, 2017
Precision experiments, such as the search for electric dipole moments of charged particles using storage rings, demand for an understanding of the spin dynamics with unprecedented accuracy.

The order analysis for the two loop corrections to lepton MDM

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
The experimental data of the magnetic dipole moment(MDM) of lepton(e, $$\mu $$ μ ) is very exact. The deviation between the experimental data and the standard model prediction maybe come from new physics contribution.

Exclusive J/ψ and ψ(2S) production inppcollisions at √s=7 TeV [PDF]

open access: yes, 2013
Exclusive J/ψ and ψ (2S) vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be σpp→J/ψ (→μ +μ −)

Production of unstable heavy neutrinos in proto-neutron stars

open access: yesPhysics Letters B, 2015
We discuss the production of a class of heavy sterile neutrinos νh in proto-neutron stars. The neutrinos, of mass around 50 MeV, have a negligible mixing with the active species but relatively large dimension-5 electromagnetic couplings. In particular, a

Rapid Microwave Plasma Engineering of HfO2/C@C Core‐Shell Fibrous Membrane Toward Flexible High‐Performance Electromagnetic Wave Absorption

open access: yesAdvanced Functional Materials, EarlyView.
Rapid microwave plasma torch engineering tunes crystal phases, carbon graphitization and oxygen‐vacancy defects in HfO2/C@C core‐shell fibrous membranes. Synergistic multi‐loss effects optimize impedance matching to deliver −65.75 dB reflection loss and a 7.37 GHz effective bandwidth for flexible electromagnetic wave absorption.
