    Updated: 2010-06-30 19:00:18
    Dartmouth researchers have discovered a potentially important piece of the quantum/classical puzzle - learning how the rules of physics in the quantum world (think smaller than microscopic) change when applied to the classical world (think every day items, like cars and trees).

  • Newswire: Fermilab - New measurements from Fermilab's MINOS experiment suggest a difference in a key property of neutrinos and antineutrinos

    Updated: 2010-06-14 15:20:00
    Batavia, Ill. - Scientists of the MINOS experiment at the Department of Energy's Fermi National Accelerator laboratory today (June 14) announced the world's most precise measurement to date of the parameters that govern antineutrino oscillations, the back-and-forth transformations of antineutrinos from one type to another. This result provides information about the difference in mass between different antineutrino types. The measurement showed an unexpected variance in the values for neutrinos and antineutrinos. This mass difference parameter, called delta m squared, is smaller by approximately 40 percent for neutrinos than for antineutrinos.
