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.

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.
