Supersymmetric Relations Among Electromagnetic Dipole Operators

, 2001
Supersymmetric contributions to all leptonic electromagnetic dipole operators have essentially identical diagramatic structure. With approximate slepton universality this allows the muon anomalous magnetic moment to be related to the electron electric ...

Model-independent study on the anomalous ττ¯γ couplings at the ILC

Nuclear Physics B, 2021
The potential of the process γγ→ττ¯γ is examined in a model-independent way using the effective Lagrangian approach for the International Linear Collider, a proposed electron-positron machine which is designed with standard configurations of 0.25 TeV ...

Testing new physics with the electron g-2 [PDF]

, 2012
We argue that the anomalous magnetic moment of the electron (a_e) can be used to probe new physics. We show that the present bound on new-physics contributions to a_e is 8*10^-13, but the sensitivity can be improved by about an order of magnitude with ...

Lepton flavor violating decays of neutral higgses in extended mirror fermion model

Nuclear Physics B, 2016
We investigate the one-loop induced charged lepton flavor violating decays of the neutral Higgses in an extended mirror fermion model with non-sterile electroweak-scale right-handed neutrinos and a horizontal A4 symmetry in the lepton sector.

Heavy fermion contributions to the anomalous magnetic dipole and quadrupole moments of theW-boson

Zeitschrift für Physik C Particles and Fields, 1987
The contribution of a massivet-quark to the anomalous magnetic moment (Δκ) and the quadrupole moment (ΔQ) of theW-boson is calculated. An upper bound of Δκ=1.5×10−2 and ΔQ=2.5×10−3 for the standard model is obtained. Additional contributions from extraE6 fermions is also discussed.

Dark sector as origin of light lepton mass and its phenomenology

Journal of High Energy Physics, 2022
We discuss a model with a dark sector, in which smallness of mass for charged leptons and neutrinos can naturally be explained by one-loop effects mediated by particles in the dark sector.

Constraints from muon g-2 and LFV processes in the Higgs Triplet Model

, 2009
Constraints from the muon anomalous magnetic dipole moment and lepton flavor violating processes are translated into lower bounds on v_Delta*m_H++ in the Higgs Triplet Model by considering correlations through the neutrino mass matrix. The discrepancy of

High Performance Room Temperature Multiferroic Properties of w‐MnSe Altermagnet

Advanced Functional Materials, EarlyView.
Using first‐principles calculations, for the first time the Altermagneto‐Ferroelectric Coupling Effect (AFCE) is proposed, which enables control of both electric polarization and spin splitting in the band structure due to polyhedral rotations. This uncovers robust multiferroicity in wurtzite MnSe at room temperature, offering an exciting route for ...
