The Production of Single t-Quarks at LEP and HERA

TL;DR

This paper explores the potential for single top-quark production at LEP II and HERA, highlighting that such events could be observable in certain dynamical models beyond the Standard Model.

Contribution

It demonstrates that single top-quark production rates could be detectable in models with dynamical fermion mass generation, unlike in the Standard Model.

Findings

Single top-quark production could be observable at LEP II and HERA in certain models.

Hierarchical and democratic symmetries suggest detectable production rates.

Standard Model predicts no observable single top-quark production.

Abstract

We study the possibility to produce single t-quarks both at LEP II and HERA. While within the Standard Model such reactions are not observable, the possibility exists in a wide class of dynamical models for the fermion mass generation. General arguments, based on hierarchical and democratic symmetries are used to arrive at t-production rates which are detectable.
