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 ...

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 ...

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 ...

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 ...

Figure 1: Hyperfine energy levels. We collect two distinct, complementary types of annihilation data. First, at the end of every trapping attempt, we rapidly turn off the confining fields and watch ...

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 ...

Physicists working on the Antihydrogen Laser Physics Apparatus (ALPHA) experiment at CERN have trapped and accumulated 15,000 antihydrogen atoms in less than 7 h. This accumulation rate is more than ...

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 ...

Of the produced antihydrogen atoms, only a few will have low enough kinetic energies (0.54 K in temperature units) to be trapped in our superconducting, multipolar, magnetic-minimum trap. The current ...

Scientists working on the big bang machine in Geneva have done the seemingly impossible: create, capture and release antimatter. The development could help researchers devise laboratory experiments to ...

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 ...

The antimatter version of the hydrogen atom - antihydrogen - could soon finally give up its secrets. Scientists expect that antihydrogen will have exactly the same properties as hydrogen; but after 80 ...
