Astrophysicists have been tracking high-energy particles from space for decades. But neutrinos are different: since they are neutral particles, they travel in a straight line, unaffected by the magnetic fields of space. Neutrinos basically give you a different eye to look at the universe and a unique probe of new physics. The current experimental knowledge on the solar neutrinos and on the terrestrial...
AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is an experiment that aims to perform the first direct measurement of the gravitational acceleration g of antihydrogen in the Earth’s field. A cold antihydrogen beam will be produced by charge exchange reaction between cold antiprotons and positronium excited in Rydberg states. Rydberg positronium (with quantum number n between 20...
