Puzzle Piece for Confirming Dark Matter Seems Unlikely Fit


In 2008, the European-Russian satellite PAMELA scanned the cosmic ray spectrum and picked up something curious — an excess of antimatter positrons. It was a startling discovery, in part because it could have been a sign of the existence of dark matter, long pursued by the worldwide physics community.
Now, in a paper submitted to Physical Review Letters, and originally published on the Internet physics archive, researchers with the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University are confirming the previous detection, and that the excess seems to grow at higher energies in the spectrum, which is consistent with many theories about how dark matter might produce positrons.
