Abstract

The thermal flux emitted by a de Sitter due to interaction with massless fields with spin is calculated by examining the field equations of these fields. The field equations are obtained by perturbing the metric with the various fields and obtaining linearised equations. The expression for the power radiated indicates the absence of spin-half particle emission.
