Beyond metric gravity: Progress on PS-200

Hyperfine Interactions Aims and scope Submit manuscript

Abstract

The reconciliation of quantum mechanics and gravity on varying distance scales requires changes to General Relativity that may have testable implications. We briefly review the status of tests with matter of the inverse square law and the principle of equivalence, then report on progress on the drift-tube measurement section of PS-200, the experiment to measure the gravitational acceleration of antiprotons.
