Measurement of the anomalous magnetic and electric dipole moments of the tau lepton [PDF]

Physics Letters B, 1998
Abstract We analyse e+e−→ττγ events using 100 pb −1 of data collected by the L3 experiment during the 1991-1995 LEP runs at the Z pole. From the energy of the photons and their isolation from the tau decay products, we determine the anomalous magnetic and electric dipole moments of the tau to be, respectively: a τ =0.004±0 ...

Research on the electromagnetic and weak dipole moments of the tau-lepton at the Bestest Little Higgs Model

European Physical Journal C: Particles and Fields, 2022
In this paper, using the Bestest Little Higgs Model (BLHM) we calculate at the one-loop level the contributions to the Anomalous Magnetic Dipole Moment (AMDM) and Anomalous Weak Magnetic Dipole Moment (AWMDM) of the tau-lepton. The implications from this

Study muon g − 2 at two-loop level in the U(1)XSSM

Journal of High Energy Physics, 2022
The new experiment data of muon g − 2 is reported by the workers at Fermilab National Accelerator Laboratory (FNAL). Combined with the previous Brookhaven National Laboratory (BNL) E821 result, the departure from the standard model prediction is about 4 ...

Systematic effects in the search for the muon electric dipole moment using the frozen-spin technique [PDF]

EPJ Web of Conferences, 2023
At the Paul Scherrer Institute (PSI) we are developing a high precision instrument to measure the muon electric dipole moment (EDM). The experiment is based on the frozen-spin method in which the spin precession induced by the anomalous magnetic moment ...

A new approach for measuring the muon anomalous magnetic moment and electric dipole moment [PDF]

Progress of Theoretical and Experimental Physics, 2019
This paper introduces a new approach to measure the muon magnetic moment anomaly $a_ = (g-2)/2$, and the muon electric dipole moment (EDM) $d_ $ at the J-PARC muon facility. The goal of our experiment is to measure $a_ $ and $d_ $ using an independent method with a factor of 10 lower muon momentum, and a factor of 20 smaller diameter storage-ring ...

A spin 1/2 particle with anomalous magnetic and electric dipole moments

Proceedings of the National Academy of Sciences of Belarus. Physics and Mathematics Series, 2022
It is Petras who first developed the P-symmetric theory for a spin 1/2 particle with an anomalous magnetic moment within the general Gel’fand – Yaglom approach. Recently, similarly it was introduced a P-asymmetric wave equation for a spin 1/2 particle which describes a particle with an electric dipole moment.

General CPT-even dimension-five nonminimal couplings between fermions and photons yielding EDM and MDM

Physics Letters B, 2016
In this letter, we examine a new class of CPT-even nonminimal interactions, between fermions and photons, deprived of higher order derivatives, that yields electric dipole moment (EDM) and magnetic dipole moment (MDM) in the context of the Dirac equation.
