The giant Large Hadron Collider at CERN's lab in Europe may be closed until 2015 but experiments will still be run there in the second half of this year on much smaller synchrotrons that examined the ...

Particle physicists at the Indian Institute of Science Education and Research (IISER) in Pune report that the most extensive hunt yet for 'vector-like leptons' – a new kind of fundamental particles ...

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 ...

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 ...

In a landmark result, the CMS collaboration reports the first observation of tau lepton pair production via photon-photon fusion in proton collisions, opening new avenues for studying these elusive ...

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 ...

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 ...
