    ALPHA experiment at CERN observes the influence of gravity on antimatter.

    ALPHA experiment at CERN observes the influence of gravity on antimatter. In a paper published earlier this autumn in Nature, the ALPHA collaboration at CERN’s Antimatter Factory shows that, within the precision of their experiment, atoms of antihydrogen – a positron orbiting an antiproton – fall to Earth in the same way as their matter

    Do opposites attract? ALPHA-g prepares to explore antimatter gravity

    Do opposites attract? ALPHA-g prepares to explore antimatter gravity Stuff falls down. This is the universal experience we all have with the gravitational interaction of matter on Earth. Yet one may still wonder if this holds true in the case of the most elusive stuff you can imagine dropping: antimatter. Might it be the case

    ALPHA publishes first measurements of quantum effects in antimatter

    ALPHA publishes first measurements of quantum effects in antimatter The ALPHA collaboration at CERN has reported the first measurements of fine structure effects and Lamb shift in the energy structure of antihydrogen that provide another test of comparison between antimatter and ordinary matter. The results, described in a paper published in Nature, show that these

    ALPHA new results: pushing the limits in antimatter research

    ALPHA new results: pushing the limits in antimatter research In a paper published this week in Nature, the ALPHA collaboration reports the most precise direct measurement of antimatter ever made, revealing the spectral structure of the antihydrogen atom in unprecedented accuracy. The result marks a new era of high precision tests between matter and antimatter

    ALPHA experiment takes a closer look at antimatter The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. The results were published in www.nature.com/nature/journal/v548/n7665/pdf/nature23446.pdf“>https://www.nature.com/nature/journal/v548/n7665/pdf/nature23446.pdf“>Nature earlier this year in August. Their measurement showed the hyperfine splitting of
