摘要
We calculate leading long-distance noncommutative corrections to the classical Schwarzschild black hole sourced by a massive noncommutative scalar field. The energy-momentum tensor is taken O(center dot(4)) in the noncommutative parameter center dot and is treated in the semiclassical (tree-level) approximation. These noncommutative corrections dominate classical post-post-Newtonian corrections if center dot > 1/M-P. However, they are still very small to be observable in present-day experiments.
