Noncommutative corrections to classical black holes

Abstract

We calculate leading long-distance noncommutative corrections to the classical Schwarzschild black hole which is sourced by a massive noncommutative scalar field. The energy-momentum tensor is taken up to $\mathcal{O}({\ell }^4)$ in noncommutative parameter, and is treated in semiclassical (tree level) approximation. These noncommutative corrections can dominate classical post-post-Newtonian corrections providing $\ell >1/M_P$, however, they are still too small to be observable in present-day experiments.
