TL;DR

This paper models the emission of primordial gravitational radiation during pre-inflation using a unified spinor field theory, providing a theoretical framework for potential future detection of such gravitational waves.

Contribution

It introduces a formalism for quantizing neutral massless bosons on curved spacetime and applies it to study graviton emission during pre-inflation.

Findings

Pre-inflation emits gravitational radiation.

The formalism describes quantization conditions for neutral massless bosons.

Potential for future detection of primordial gravitational waves.

Abstract

We obtain the equation that describe the conditions of quantization for neutral massless bosons on an arbitrary curved space-time, obtained using a particular theoretical formalism developed in a previous work\cite{MM}. In particular, we study the emission of neutral massless $(1, 2)\hbar$-spin bosons during pre-inflation using the recently introduced unified spinor field theory. We conclude that during pre-inflation (which is governed by an vacuum equation of state), is emitted gravitational radiation, which could be detected in the future, as primordial gravitational radiation.
