In the standard model of particle physics, every particle has its own antimatter counterpart — particles of quasi-identical fundamental properties, the most well-known of which have opposite magnetic ...

Researchers at CERN have created and trapped antihydrogen in an attempt to study the underpinnings of the standard model of physics. Antihydrogen is made of antiparticles, specifically an antiproton ...

WEST LAFAYETTE, Ind. — The international collaborators of the ALPHA-2 experiment have measured the charge of antihydrogen to be zero with the greatest precision yet, narrowing the possibilities of ...

Antihydrogen forms an ideal study subject for deciphering the secrets of fundamental physics due to it being the most simple anti-matter atom. However, keeping it from casually annihilating itself ...

The ALPHA collaboration at CERN reports an important milestone on the way to measuring the properties of antimatter atoms. This follows news reported in June last year that the collaboration had ...

Physicists working at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have succeeded in trapping antihydrogen – the antimatter equivalent of the hydrogen atom – a ...

How different are matter and antimatter? This is a question that gets at the heart of modern particle physics and early-universe cosmology. The objects of everyday experience are made of ordinary ...

Physicists at CERN have found the value of the Lamb shift in antihydrogen closely agrees with the value in hydrogen This reaffirms a fundamental symmetry of nature Yet it can't tell us why we and the ...

The first spectroscopy measurements of an atom of antimatter have been made by an international team of physicists working on the ALPHA experiment at CERN. The work is an important step towards ...

Antihydrogen, a positron bound to an antiproton, is the simplest antiatom. Its counterpart—hydrogen—is one of the most precisely investigated and best understood systems in physics research.

Getting to the heart of antimatter: an artist's concept showing a trapped antihydrogen atom being released after 1000 seconds. The new proposal allows for such trapped antimatter to be laser cooled ...

Trapping antihydrogen atoms at the European Organization for Nuclear Research (CERN) has become so routine that physicists are confident that they can soon begin experiments on this rare antimatter ...
