Antimatter study to benefit from recipe for ten-fold spatial compression of plasma
An international team of physicists studying antimatter have now derived an improved way of spatially compressing a state of matter called non-neutral plasma, which is made up of a type of antimatter particles, called antiprotons, ...
In quest of the coldest possible antihydrogen
Currently, one of the major goals in ultracold science is to cool antihydrogen atoms to as close to absolute zero as possible. Ultracold antihydrogen would pave the way toward ultraprecise antimatter experiments that could ...
Physicists zoom in on mysterious 'missing' antimatter
When the Universe arose some 13.7 billion years ago, the Big Bang generated matter and antimatter particles in mirroring pairs. So the reigning physics theory goes.
How the SuperNEMO experiment could help solve the mystery of the origin of matter in the universe
The Savoy region of France is best known for its fir-lined ski slopes and picturesque Alpine villages. Less known is the fact that, deep beneath some of these slopes, scientists are investigating one of the greatest mysteries ...
Observation of the hyperfine spectrum of antihydrogen
A Canadian-led investigation has opened a new chapter in antimatter research. In a study published today in Nature, the ALPHA Collaboration, which includes 50 physicists from 17 institutions, reports the first detailed observation ...
Scientists solve mystery of how most antimatter in the Milky Way forms
A team of international astrophysicists led by The Australian National University (ANU) has shown how most of the antimatter in the Milky Way forms.
Raising the (G)bar for antimatter exploration
The absence of antimatter in the universe is a long-standing jigsaw puzzle in physics. Many experiments have been exploring this question by finding asymmetries between particles and their antimatter counterparts.
LHCb observes an exceptionally large group of particles
The LHCb experiment at CERN is a hotbed of new and outstanding physics results. In just the last few months, the collaboration has announced the measurement of a very rare particle decay and evidence of a new manifestation ...
New source of asymmetry between matter and antimatter
The LHCb experiment has found hints of what could be a new piece of the jigsaw puzzle of the missing antimatter in our universe. They have found tantalising evidence of a phenomenon dubbed charge-parity (CP) violation in ...
