Cosmic Antiparticle: Latest Results from the Alpha Magnetic Spectrometer on the International Space Station
The Alpha Magnetic Spectrometer (AMS) is a precision particle physics detector on the International Space Station conducting a unique, long-duration mission of fundamental physics research in space. In this talk, I will present the latest AMS results on the fluxes of cosmic positrons and antiprotons. These latest results up to the TeV region reveal unique properties of cosmic elementary particle fluxes and indicate the existence of a primary source of high-energy antiparticles such as dark matter annihilation. I will also report on the recent progress of antideuteron measurement and its future prospects. The latest results from AMS, together with its future measurements, continue to provide unique insights into studying the origin of dark matter and antimatter, and exploring new physics phenomena in the cosmos.
