Unparticle physics in e^+ e^- annihilation

TL;DR

This paper investigates how unparticle physics influences electron-positron annihilation into light meson pairs, revealing sensitivity to unparticle scaling dimensions below 1.4, thus providing potential experimental signatures.

Contribution

It introduces a novel analysis of fermionic unparticle effects on e^+ e^- annihilation cross-sections into meson pairs, highlighting the sensitivity to the unparticle scaling dimension.

Findings

Cross-section depends on unparticle scaling dimension d_U<1.4

Fermionic unparticles significantly affect e^+ e^- -> PP processes

Potential for experimental detection of unparticle effects

Abstract

In the recent past,unparticle physics effects have been explored in detail in both the fermionic and bosonic sectors. We have used fermionic unparticles to study the cross-section of electron-positron annihilation to light pseudo-scalar meson pairs e^+e^- ->PP. We show that this cross-section is sensitive to the scaling dimension d_U<1.4.
