• Resumen

  • The article reports on axions. They contribute to the dark matter that constitutes 22 percent of the universe. Axions produced during the big bang could still be present. According to a paper published in March, 2006, axions produced in the laboratory may have been detected for the first time. They are difficult to detect because of their very low mass and because they are electrically neutral and only interact partially with other particles. INSET: SAVING A SYMMETRY.
