Mass function and particle creation in Schwarzschild-de Sitter spacetime    [PDF]

Sourav Bhattacharya, Amitabha Lahiri
We construct a mass function for the Schwarzschild-de Sitter black hole spacetime everywhere in between the black hole and the cosmological event horizon. The mass function is positive definite, continuous and monotonically increasing with the radial distance from the black hole horizon and can be related to the geodesic motion. Finally, choosing a suitable timelike hypersurface in between the two horizons, we study particle creation for a massless quantum scalar field in this spacetime.
