Fifty experts on nuclear physics, particle physics and astrophysics met at CERN from 9 to 13 June to discuss how to use ...

Here we look at what leptons are, how they fit in the Standard Model of particle physics, ... An example of leptons involved in particle decay is the decay of a neutron.

Fornal and Grinstein determined that, in the simplest scenario, the hypothetical dark matter particle’s mass must fall between 937.9 and 938.8 mega-electron volts, and that a neutron decaying ...

A four-neutron particle called a tetraneutron, which forms very briefly as a “resonance”, has been observed in Japan by researchers who collided highly neutron-rich nuclei with protons. The detection ...

Above: A neutron star. Credit: Casey Reed/Penn State University. You may have heard that CERN announced the discovery of a strange particle known as Z(4430). A paper summarizing the results has been ...

Beryllium-14’s halo is made of four neutrons, so the researchers expected to see that halo break apart and become four individual neutrons. That would have been detected as four distinct signals.

The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and the weak force Particle physics describes the universe at the ...

This sea of neutrons that makes up a neutron star is so dense that if a mere tablespoon of it were brought to Earth, it would weigh over 1 billion tons. That's about the same weight as Mount Everest.

Chadwick discovers the neutron 1932. For four years, James Chadwick was a prisoner of war in Germany. When World War I ended, he returned to his native England to rejoin the mentor of his ...
