Optimal observable to measure the imaginary component of the τ anomalous weak-magnetic dipole moment

open access: closedPhysics Letters B, 1997
The feasibility of measuring the imaginary component of the τ anomalous weak-magnetic dipole moment (aτW) is discussed. From a sample of data comparable to that obtained in the period 90–95 by one of the LEP experiments the expected error in the anomalous weak-magnetic dipole moment for the π−π+, π±ϱ∓ and ϱ−ϱ+ final states is estimated to be |Im(aτW)| <

Specification and design of a radial vane silicon tracker for a new measurement of the muon anomalous magnetic moment g-2 and electric dipole moment at J-PARC

open access: closed2011 IEEE Nuclear Science Symposium Conference Record, 2011
A new measurement of the anomalous magnetic moment (g-2) and electric dipole moment (EDM) of the positive muon at J-PARC is proposed. In this experiment, we plan to use a radial vane silicon detector for detecting muon decay positrons. Specification and design study of the detector has been promoted.

Theory of Anomalous Magnetic Dipole Moments of the Electron

2014
The anomalous magnetic dipole moment of the electron, the so-called electron \(g-2\), provides us with a high-precision test of quantum electrodynamics (QED), which is the relativistic and quantum-mechanical generalization of electromagnetism, and helps to determine the value of the fine structure constant \(\alpha \), one of the fundamental physical ...

Electron and muon anomalous magnetic dipole moment in the 3-3-1 model with heavy leptons

open access: closed, 2018
Nós calculamos, no contexto do modelo 3-3-1 com léptons pesados carregados, vínculos sobre alguns dos parâmetros das partículas extras do modelo ao impor que suas contribuições aos fatores (g-2) do elétron e do múon estejam de acordo com os dados experimentais dentro de 1 sigma - 3 sigma.

On exact allowance for masses, anomalous magnetic moments, and electric dipole moments of the neutrinos in the ?1 ? ?1?2�?2 reaction in an external field

Soviet Physics Journal, 1992
The probability of the process ν1 → ν1ν2¯ν2 in the field of a plane wave is calculated in the general case with allowance for masses, anomalous magnetic moments, and electric dipole moments of the neutrinos. In special cases, earlier results are confirmed.
