Road transport of trapped antiprotons

Abstract Low-energy antiprotons confined in ultrahigh-vacuum Penning traps 1 enable precision investigations of charge, parity and time-reversal (CPT) invariance 2 to test the fundamental symmetry between matter and antimatter. These studies are driven by the search for physics b...

Generation of a high-intensity, superthermal muonium beam for gravity and laser spectroscopy experiments

Abstract The universality of free fall, a cornerstone of Einstein’s theory of gravity, has so far only been tested with neutral composite states of first-generation standard model particles, such as atoms, neutrons and antihydrogen. Muonium, the bound state of a positively charge...
