Emission of primordial bosonic radiation during inflation

摘要

We study the emission of neutral massless (1, 2) h-spin bosons during power-law inflation using unified spinor field theory. We show that during inflation, gravitons and photons were emitted with wavelengths (on physical coordinates) that increase with the Hubble radius lambda(Ph) similar to a/H. The quantised action related to these bosons is calculated and determined to be a fraction of the Planck constant.
