Ultraheavy particles at the LHC or a next-generation collider?

TL;DR

The paper explores the possibility that ultraheavy particles with multi-TeV masses, potentially detectable at the LHC or future colliders, could be linked to early universe processes responsible for the cosmological constant.

Contribution

It proposes a theoretical connection between ultraheavy particles and the cosmological constant, suggesting their potential detectability at high-energy colliders.

Findings

Ultraheavy particles could exist with multi-TeV masses.

Detection at colliders could shed light on early universe physics.

Link between cosmological constant and new particle physics.

Abstract

If the effective cosmological constant $\Lambda$ of the present universe is due to physical processes in the early universe operating at temperatures just above the electroweak energy scale, it is possible that new particles with multi-$\text{TeV}$ masses exist. These ultraheavy particles may (or may not) show up at the Large Hadron Collider (LHC) or a next-generation proton-proton collider. If they do, they may provide new insights into the early universe and fundamental physics.
