Massless fields infinitely degenerating with respect to the helicity and their effects in astrophysics

TL;DR

This paper explores how tachyon fields, described as infinitely degenerate massless fields with respect to helicity, can influence cosmological phenomena like universe expansion, dark energy, and matter-antimatter asymmetry without violating causality.

Contribution

It introduces a novel description of tachyon fields as infinitely degenerate massless fields and links their effects to cosmological observations and symmetry breaking.

Findings

Tachyon fields can be represented by phase factors affecting universe expansion.

The model explains dark energy and accelerated expansion without contradicting causality.

An asymmetry between particles and anti-particles is derived from the phase factor.

Abstract

A tachyon field having a negative squared-mass $-m_t^2$ can be described in terms of massless fields degenerating infinitely with respect to the helicity. The degeneracy leads symmetry breakings of space-time. This picture for the tachyon does not contradict causality. The tachyon vector-field is quenched from the interactions with matter fields, and the effects can be represented by a phase factor. The accelerated expansion of the universe and the dark energies are interpreted in terms of the phase factor. An asymmetry between the distribution of particles and that of anti-particles in the universe is also derived from the phase. Membranes can be described by the tachyon wave packet.
