The Alpha Magnetic Spectrometer (AMS) collaboration will present today the latest results in its quest to understand the origin of cosmic rays and dark matter. These intriguing results will be shared and discussed during the “AMS days” starting today at CERN with many of the world’s leading theoretical physicists and principal investigators of some of the major experiments exploring the field of cosmic-ray physics. The main objective of this scientific exchange is to understand the interrelation between AMS results and those of other major cosmic-ray experiments and current theories.
“I am very pleased that so many of the world's leading scientists are interested in AMS results and are coming to CERN for this meeting,” said AMS spokesperson Samuel Ting.
In particular, AMS is presenting unexpected new results on the antiproton/proton ratio in the cosmic rays, and on the proton and helium fluxes. Pre-existing models of ordinary cosmic rays cannot explain the AMS results. These new observations may provide important information on the understanding of cosmic-ray production and propagation. It is possible that the results may be explained by new astrophysical sources or new acceleration and propagation mechanisms, and the latest AMS results are also consistent with dark matter collisions.
