Lepton flavor violating Higgs decays and unparticle physics

TL;DR

This paper predicts the branching ratios of lepton flavor violating Higgs decays mediated by scalar unparticles, showing they can be significantly large depending on unparticle parameters.

Contribution

It introduces a novel calculation of LFV Higgs decay rates via scalar unparticles, highlighting their sensitivity to unparticle scaling dimensions.

Findings

Branching ratios can reach up to 10^{-4} for certain parameters.

Decay rates are highly sensitive to the unparticle scaling dimension.

Potentially observable signals in future experiments.

Abstract

We predict the branching ratios of the lepton flavor violating Higgs decays H^0->e^{\pm} \mu^{\pm}, H^0-> e^{\pm} \tau^{\pm} and H^0->\mu^{\pm} \tau^{\pm} in the case that the lepton flavor violation is carried by the scalar unparticle mediation. We observe that their branching ratios are strongly sensitive to the unparticle scaling dimension and they can reach to the values of the order of $10^{-4}$, for the heavy lepton flavor case and for the small values of the scaling dimension.
