So, to Sum the Tauon: It is the heaviest lepton in the whole particle zoo at nearly 3,500 times larger than the smallest of the lepton, the electron.

The discovery of the Higgs boson hasn’t led to an explosion of new physics as many predicted. Now, some scientists think that hidden physics may be hiding beyond LHC’s view.

Some money could be saved if we build the circular lepton and proton colliders one after the other in the same tunnel, which would essentially provide a future for experimental particle physics ...

The final results from many different particle accelerator experiments have definitively showed that the Z-boson decays to charged leptons about 10% of the time, neutral leptons about 20%, and ...

The Standard Model of particle physics describes the fundamental particles and forces, along with the mathematical framework that governs their interactions. According to quantum electrodynamics (QED) ...

Under the Standard Model of particle physics it's classified as a "lepton." Other leptons include electrons, the negatively charged particles that make up atoms, with protons and neutrons.

(Courtesy: CERN) Lepton flavour universality is a principle in particle physics that concerns how all leptons (electrons, muons and taons) should interact with the fundamental forces of nature. The ...

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 ...

On this page of his logbook, Perl plotted the curves you’d expect for a three-body decay and two different kinds of two-body decays. When he looked at where his data points fell, he was convinced that ...

Among these deviations are the multi-lepton anomalies. "From the multi-lepton anomalies one can predict the existence of a new Higgs-like boson, somewhat heavier than the one discovered in 2012.

The first lepton surprise showed up in results announced in 2012 from the BaBar experiment at the SLAC National Accelerator Laboratory in Menlo Park, Calif. BaBar's particle accelerator rammed ...
