  1. Antimatter - CERN

    science physics antimatter Antimatter Antimatter Paul Dirac (Image: Wikimedia) In 1928, British physicist Paul Dirac wrote down an equation that combined quantum theory and special …

  2. The matter-antimatter asymmetry problem - CERN

    The matter-antimatter asymmetry problem The Big Bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe? The …

  3. Storing antihydrogen - CERN

    And because antimatter annihilates in a flash of energy when it interacts with regular matter, storing it presents a challenge. Creating Antihydrogen The antimatter counterpart to the …

  4. Probing dark matter using antimatter - CERN

    Nov 13, 2019 · Dark matter and the imbalance between matter and antimatter are two of the biggest mysteries of the universe. Astronomical observations tell us that dark matter makes up …

  6. The Antiproton Decelerator - CERN

    The Antiproton Decelerator (AD) is a unique machine that produces low-energy antiprotons for studies of antimatter, and “creates” antiatoms. A proton beam coming from the PS (Proton …

  7. ALPHA experiment at CERN observes the influence of gravity on …

    Sep 27, 2023 · CERN’s Antimatter Factory is a unique facility in the world for producing and studying antimatter. Two other experiments at this facility, AEgIS and GBAR, share with …

  8. A new piece in the matter–antimatter puzzle - CERN

    Mar 21, 2025 · Update 16 July 2025 The paper ‘Observation of charge-parity symmetry breaking in baryon decays’ originally released on 21 March 2025 has been published today in the …

  9. An antimatter beam open for booking - CERN

    Jun 5, 2025 · CERN’s antimatter factory produces low-energy (i.e. 'slow') antiprotons in order to “manufacture” and study antimatter. To achieve this, two decelerators, the Antiproton …

  10. Breakthrough in antimatter production - CERN

    Nov 18, 2025 · In a paper published today in Nature Communications, researchers at the ALPHA experiment at CERN’s Antimatter Factory report a new technique that allows them to produce …
