Chiral tensor particles in the early Universe

TL;DR

This paper reviews the theoretical and experimental status of chiral tensor particles within an extended electroweak model, exploring their early Universe interactions, cosmological effects, and potential for detection at future colliders.

Contribution

It provides a comprehensive analysis of chiral tensor particles' role in the early Universe and evaluates their cosmological and experimental implications.

Findings

Chiral tensor particles can exist without conflicting with cosmological constraints.

Their presence accelerates the Friedmann expansion due to increased density.

Detection prospects at new colliders are promising based on their characteristic interactions.

Abstract

The status of the chiral tensor particles in the extended electroweak model, their experimental constraints, signatures and the possibilities for their detection at the new colliders are reviewed. The characteristic interactions of the chiral tensor particles in the early Universe plasma and the corresponding period of their cosmological influence is determined. The dynamical cosmological effect, namely the speeding of the Friedmann expansion due to the density increase caused by the introduction of the new particles, is evaluated. It is shown that the existence of the chiral tensor particles is allowed from cosmological considerations and welcomed by the particle physics phenomenology.
