Let's get something out of the way: some of the latest results from the LHC are likely to be a statistical fluke and will vanish as the current, high-energy run starts pumping out data in earnest. In ...

Building experimental evidence suggests that the electron, muon and tau may feel different forces. When the tau lepton was discovered in the 1970s, it didn’t resolve any outstanding mysteries—it ...

The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences Electrons with 'colleagues' - other leptons - are one of many products of collisions observed in the LHCb experiment ...

A team has succeeded in computing how atomic nuclei of the Calcium element behave in collisions with electrons. Results agree very well with available experimental data. For the first time, a ...

Elisabetta Barberio receives funding from the ARC. So what are leptons? First, let’s start with the basics. Matter is made up of atoms, and atoms are made of electrons and nuclei, bound by the ...

Nearly a decade after the Higgs boson's discovery was announced to the world, physicists at the European Organization for Nuclear Research (CERN) are still breaking down the fundamental buildings ...

Charged leptons are a breed of elementary particle that comes in three masses: the lightweight electron, responsible for the electricity in our homes; the middle-weight muon; and the heavy tau. Two ...

We all like hearing about the biggest and the smallest, the heaviest and the lightest, as these categories represent the extremes of the universe…and they usually they are great for comparisons. Meet ...

Editor's Note: This story was updated on Friday Sept. 11 at 2:45 p.m. E.T. Trouble is brewing in the orderly world of subatomic physics. New evidence from the world's largest atom smasher, the Large ...

The quarks, antiquarks, and gluons of the standard model have a color charge, in addition to all the other properties like mass and electric charge that other particles and antiparticles possess. All ...
