The scalar unparticle effect on the charged lepton electric dipole moment

TL;DR

This paper investigates how scalar unparticles influence the electric dipole moments of charged leptons, revealing sensitivity to unparticle scaling dimensions and constraining parameters based on experimental limits.

Contribution

It provides the first detailed analysis of scalar unparticle effects on charged lepton EDMs and constrains model parameters using current experimental data.

Findings

EDMs are highly sensitive to unparticle scaling dimension d_u

Current experimental limits restrict free parameters of the model

Scalar unparticle mediation can induce measurable EDMs in charged leptons

Abstract

We study the charged lepton electric dipole moment which is induced by the scalar unparticle mediation and we predict the appropriate range for the free parameters appearing in the effective lagrangian which drives the unparticle-standard model lepton interactions. We observe that the charged lepton electric dipole moment is strongly sensitive to the scaling dimension d_u of the unparticle and the new couplings in the effective interaction. Furthermore, we see that the current experimental limits of charged lepton electric dipole moments can ensure an appropriate range for these free parameters.
