Single production of the doubly charged scalar in the littlest Higgs model

TL;DR

This paper investigates the production of doubly charged scalars in the littlest Higgs model across different collider types, highlighting the potential for detection at future high-energy linear colliders like the ILC.

Contribution

It provides a detailed analysis of the single production mechanisms of doubly charged scalars in the littlest Higgs model at various colliders, emphasizing the higher detectability at the ILC.

Findings

Doubly charged scalars can be produced abundantly at future colliders.

Production cross section is higher at the ILC compared to LHC and THERA.

Signatures of these scalars should be detectable in upcoming experiments.

Abstract

Single production of the doubly charged scalars $\Phi^{\pm\pm}$ via $e\gamma$, $ep$ and $pp$ collisions is studied in the context of the little Higgs$(LH)$ model. Our numerical results show that the new particles $\Phi^{\pm\pm}$ can be abundantly produced and their possible signatures should be detected in future high energy linear $e^{+}e^{-}$ collider$(ILC)$. The cross section for single production of $\Phi^{\pm\pm}$ at the $LHC$ is much smaller than that at the $ILC$ or the $THERA$.
