Graviton Propagator in a 2-Parameter Family of de Sitter Breaking Gauges

Understand

We formulate the graviton propagator on de Sitter background in a 2-parameter family of simple gauges which break de Sitter invariance.

• Explicit results are derived for the first order perturbations in each parameter.
• These results should be useful in computations to check for gauge dependence of graviton loop corrections.
