Unparticle Physics in the Moller Scattering

TL;DR

This paper explores how hypothetical unparticles could influence Moller scattering, deriving formulas and setting limits on their couplings based on simulated collider data at various energies and luminosities.

Contribution

It provides the first analytic expressions for unparticle effects in Moller scattering and establishes experimental bounds on unparticle couplings at different collider configurations.

Findings

Limits on vector unparticle couplings are more stringent than axial ones.

Higher energies and luminosities improve the sensitivity to unparticle effects.

Analytic formulas for unparticle contributions to scattering amplitudes are derived.

Abstract

We investigate the virtual effects of vector unparticles in the Moller scattering. We derive the analytic expression for scattering amplitudes with unpolarized beams. We obtain 95% confidence level limits on the unparticle couplings $\lambda_{V}$ and $\lambda_{A}$ with integrated luminosity of $L_{int}=50, 500 fb^{-1}$ and $\sqrt{s}=100, 300$ and 500 GeV energies. We show that limits on $\lambda_{V}$ are more sensitive than $\lambda_{A}$.
