Abstract:
We study a massive scalar field theory in de Sitter space. Using a worldline instanton approach, we calculate the pair creation probability in the weak-field limit. In addition to the exponential factor, we derive the pre-exponential factor. In this method, the pair creation probability for an odd-dimensional space vanishes. We find the leading contribution to the two-point correlator in the $\phi^3$ theory.
Keywords:
quantum field in curved space, de Sitter space.
