Production of the triply heavy $\Omega_{ccc}$ and $\Omega_{bbb}$ baryons at $e^+e^-$ colliders

TL;DR

This paper calculates the production rates of the triply heavy baryons $ ext{Omega}_{ccc}$ and $ ext{Omega}_{bbb}$ at electron-positron colliders using NRQCD, finding that direct observation at current energies is challenging.

Contribution

It provides exact leading-order calculations of total and differential cross sections for $ ext{Omega}_{ccc}$ and $ ext{Omega}_{bbb}$ production at $e^+e^-$ colliders using NRQCD.

Findings

Production cross sections are small, making direct observation difficult.

Exact calculations at different collider energies were performed.

Results suggest challenges in detecting these baryons at current colliders.

Abstract

Non-relativistic quantum chromodynamics (NRQCD) factorization formulism is an important approach to investigate the production of the heavy quarkonium. In this paper, we study the production of the $\Omega_{ccc}$ and $\Omega_{bbb}$ at the $e^+e^-$ collider, using the NRQCD factorization formulism. We calculate the total and differential cross sections exactly of the processes, $e^+e^-\rightarrow \gamma^*/Z^*\rightarrow \Omega_{ccc}\bar{c}\bar{c}\bar{c}$ and $e^+e^-\rightarrow \gamma^*/Z^*\rightarrow \Omega_{bbb}\bar{b}\bar{b}\bar{b}$, in the leading order at the $e^+e^-$ colliders with different energies. The results show that it is hard to observe them at the $e^+e^-$ collider directly.
