Transverse spin asymmetries at the EIC as a probe of anomalous electric and magnetic dipole moments
Physical Review D, 2023 We show that inclusive single-spin asymmetries (SSAs) with transversely polarized protons or electrons at a future electron ion collider (EIC) are sensitive to new physics contributions to electroweak dipole operators of electrons and quarks.

Anomalous magnetic and electric dipole moments of the tau [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 This paper reviews the theoretical predictions for and the experimental measurements of the anomalous magnetic and electric dipole moments of the tau lepton. In particular, recent analyses of the $\eettg$ process from the L3 and OPAL collaborations are described.

Revisiting the scalar leptoquark $$(S_1)$$ ( S 1 ) model with the updated leptonic constraints
European Physical Journal C: Particles and Fields, 2023 The Standard Model, if extended to the energy scale of $${\mathscr {O}}(1)$$ O ( 1 ) TeV, the known particle spectrum could be augmented with a scalar leptoquark.

Studies on the anomalous magnetic and electric dipole moments of the tau-neutrino in pp collisions at the LHC [PDF]
The European Physical Journal A, 2019 In this paper the production cross section $pp\rightarrow ( , Z) \to _ \bar _ +X$ in $pp$ collisions at $\sqrt{s}=8, 13, 14, 33TeV$ is presented. Furthermore, we estimate bounds at the $95\%C. L.$ on the dipole moments of the tau-neutrino using integrated luminosity of ${\cal L}=20, 50, 100, 200, 500, 1000, 3000 fb^{-1}$ collected with the ...

Bounds on radii and anomalous magnetic dipole moments of quarks and leptons from LEP, SLC and HERA [PDF]
Zeitschrift für Physik C Particles and Fields, 1995 Leptons, quarks and gauge bosons are assumed to be pointlike particles in the Standard Model. Stringent bounds on the radii of quarks and leptons and their weak anomalous magnetic moments can be derived from the high-precision measurements at LEP and SLC. We find a model-independent bound ofR≲10−17 cm for quark and lepton radii.
