# Energy frontier lepton-hadron colliders, vector-like quarks and leptons, preons and so on

## TL;DR

This paper discusses the significance of future energy frontier lepton-hadron colliders, explores the potential existence of new heavy quarks and leptons, and advocates for preonic matter and specific facilities in Turkey.

## Contribution

It highlights the importance of upcoming colliders, presents arguments for new heavy particles and preonic matter, and recommends strategic facilities for Turkey's scientific development.

## Key findings

- Emphasizes the role of LHC and FCC-based colliders in future discoveries.
- Argues for the existence of new heavy isosinglet quarks and leptons.
- Supports the development of specific facilities like Super-Charm factory in Turkey.

## Abstract

First of all, an importance of the LHC and FCC based energy frontier lepton-hadron and photon-hadron colliders is emphasised. Then arguments favoring existence of new heavy isosinglet down-type quarks and vector-like isosinglet or isodoublet leptons are presented, following by historical arguments favoring new (preonic) level of matter. The importance of Super-Charm factory and GeV energy proton linac for Turkey national road map is argued. Finally, several recommendations for ESPP2020 are suggested.
