Are there indications of compositeness of leptons and quarks in CERN LEP data?

TL;DR

This paper investigates the possibility of lepton and quark compositeness through the preon-trinity model, predicting new heavy particles that could be produced at CERN LEP energies, and analyzes existing data to estimate their masses.

Contribution

It introduces the preon-trinity model predicting new heavy leptons and quarks, and estimates their possible masses based on CERN LEP data analysis.

Findings

Predicted new particles are lighter than the top quark.

Some of these particles could be produced in $e^{+}e^{-}$ annihilations at CERN LEP.

Empirical analysis suggests specific mass ranges for these particles.

Abstract

The ``preon-trinity'' model for the compositeness of leptons, quarks and heavy vector bosons predicts several new heavy leptons and quarks. Three of them can be produced in $e^{+}e^{-}$ annihilations at CERN LEP energies, since they can be created out of a system of three preons and their antipreons, where three preons form a heavy lepton or quark, while the other three go into a normal lepton or quark. In fact, these new particles are predicted to be lighter than the top quark, while the top itself cannot be produced this way, due to its particular preon substructure. The empirical situation is analyzed, and the most likely masses are estimated.
