The effect of the scalar unparticle on the production of Higgs - radion at high energy colliders

TL;DR

This paper investigates how scalar unparticles influence Higgs-radion production at high-energy colliders, analyzing cross-sections in various collision types and highlighting the significant impact of unparticle parameters on production rates.

Contribution

It provides a detailed calculation of Higgs-radion production cross-sections considering scalar unparticles within the Randall-Sundrum model, emphasizing the dependence on unparticle parameters.

Findings

Cross-sections vary strongly with collision energy, unparticle scaling dimension, and energy scale.

Scalar particle pair production cross-sections are significantly larger than associated production.

Numerical results demonstrate the substantial impact of unparticle parameters on collider phenomenology.

Abstract

An attempt is made to present the influence of the scalar unparticle on some scattering processes in the Randall - Sundum model. The contribution of the scalar unparticle on the production of Higgs - radion at high energy colliders is studied in detail. We evaluate the production cross-sections in the electron-positron ($e^{+}e^{-}$), photon-photon ($\gamma\gamma$) and gluon-gluon ($gg$) collisions, which depend strongly on the collision energy $\sqrt{s}$, the scaling dimension $d_{U}$ of the unparticle operator $\mathcal{O}_{U}$ and the energy scale $\Lambda_{U}$. Numerical evaluation shows that the cross - sections for the pair production of scalar particles are much larger than that of the associated production of the scalar particle with unparticle in the same condition
