Antimatter captivates the popular imagination. Beatriz Gato-Rivera, a former CERN fellow in theoretical physics and now a researcher at the Spanish National Research Council, recently published a note...
As reported today in Nature, the technique promises to reduce the time needed to cool antiprotons from hours to seconds.
Laser-cooling opens the door to considerably more precise measurements of antihydrogen’s internal structure and gravitational interactions.
Precise knowledge of the moment anti-atoms are produced will allow new tests of the weak equivalence principle.
The latest spectral measurements of antihydrogen atoms confirm that a key portion of QED holds up in both matter and antimatter.
Working at CERN’s Antiproton Decelerator, the international BASE team has set the first laboratory limits on the interaction between antimatter and dark-matter axions
ALPHA-g and GBAR have begun campaigns to check whether antimatter falls under gravity at the same rate as matter.
The collaboration has reported the first measurement of the Lyman-alpha transition.
The 13th Low Energy Antiproton Physics (LEAP) conference was held from 12–16 March at the Sorbonne.
Measurements of the hydrogen’s spectral structure agree with theoretical predictions to a few parts in 1015. Researchers have long sought to match this precision for antihydrogen.
