Antimatter Gravity and Antihydrogen Production
Certain modern theories of gravity predict that antimatter will fall differently than matter in the Earth’s gravitational field. However, no experimental tests of gravity on antimatter exist and all conclusions drawn from experiments on matter depend, at some level, on a specific model. We have proposed a direct measurement that would compare the gravitational acceleration of antiprotons to tha...
متن کاملAntimatter interferometry for gravity measurements.
We describe a light-pulse atom interferometer that is suitable for any species of atom and even for electrons and protons as well as their antiparticles, in particular, for testing the Einstein equivalence principle with antihydrogen. The design obviates the need for resonant lasers through far-off resonant Bragg beam splitters and makes efficient use of scarce atoms by magnetic confinement and...
متن کاملAn Antihydrogen Interferometer for Measuring Antimatter Gravity
The gravitational force on antimatter has never been directly measured, largely because electromagnetic forces overwhelm gravitational forces and no form of low-energy neutral antimatter has been available. However, the technology to make low-energy antihydrogen is currently being developed. We have designed an atomic interferometer that can measure the force of gravity on hydrogen or antihydro...
متن کاملCPT symmetry and antimatter gravity in general relativity
The gravitational behavior of antimatter is still unknown. While we may be confident that antimatter is self-attractive, the interaction between matter and antimatter might be either attractive or repulsive. We investigate this issue on theoretical grounds. Starting from the CPT invariance of physical laws, we transform matter into antimatter in the equations of both electrodynamics and gravita...
متن کاملMeasuring Antimatter Gravity with Muonium IIT - CAPP - 14 - 03 Daniel
The gravitational acceleration of antimatter, ḡ, has never been directly measured and could bear importantly on our understanding of gravity, the possible existence of a fifth force, and the nature and early history of the universe. Only two avenues for such a measurement appear to be feasible: antihydrogen and muonium. The muonium measurement requires a novel, monoenergetic, low-velocity, hori...
