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 ...

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 ...

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 ...

The universe is a complex and intricate place. We can move easily through air and yet not through a wall. The sun transmutes one element to another, bathing our planet in warmth and light. Radio waves ...

All the matter we know of in the Universe is made up of Standard Model particles. Photons and neutrinos zip through the Universe all the time, far outnumbering all the other particles. Normal, ...

Physicists are hunting for an elusive particle that swings both ways, and if they find it, it could explain several bizarre results found at atom smashers around the world. In modern physics, matter ...

One of the most important observations in particle physics was the discovery in 1964 of the Omega-minus baryon at Brookhaven National Laboratory. In the two decades leading up to this point over 27 ...
