Latest Lepton Stories
Astrophysicists believe that about 80 percent of the substance of our universe is made up of mysterious “dark matter” that can’t be perceived by human senses or scientific instruments.
Although Dark Energy and Dark Matter appear to constitute over 95 percent of the universe, nobody knows of which particles they are made up. Astrophysicists now crossed one potential Dark Matter candidate – the Dark Photon or U boson – off the list in top position.
It’s been just over one year since the discovery of the Higgs boson was all but confirmed, but researchers now believe that there might be particles even smaller that have yet to be discovered.
Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe works on subatomic scales.
Fermilab team of physicists analyze two-lepton data.
New, higher precision data that could only have been gathered at the Department of Energyâ€™s Thomas Jefferson National Accelerator Facility (Jefferson Lab) shows the Theta-plus pentaquark doesnâ€™t appear in another place it was expected. This intriguing finding contradicts evidence previously presented by Jefferson Lab researchers that they had sighted a pentaquark, a particle built of five quarks.
