The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

Does the proton decay? While this was a famous prediction of Grand Unified Theories (GUTS) developed in the 1970s and 1980s, experimentalists have ruled it out—or rather, put lower limits on its mean ...

The Isotope Separator On-Line facility (ISOLDE) directs a proton beam from the Proton Synchrotron Booster (PSB) onto specially developed thick targets, producing low-energy beams of radioactive nuclei ...

According to the Standard Model, protons are inherently stable and will not decay into other particles. Other theories, however, contend that they do. If true, that means that in the astronomically ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons.

Two thousand feet under the shores of Lake Erie, in a six-story salt cavern, one of the most sophisticated light detectors ever constructed is waiting. Every second, several particles speed through ...

At the Large Hadron Collider (LHC), physicists accelerate particles to the highest energies and in the greatest numbers that humanity has ever achieved. We smash them together at greater than ...
