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

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 ...

The subatomic particle can either be a composite particle such as a proton, neutron, or meson or an elementary particle such as an electron, photon, or muon.

To continue their studies, the researchers plan to use the UK’s ISIS Neutron and Muon Source to explore ways of combining neutron Airy beams with other structured neutron beams (such as helical waves ...

No protons needed? Possible discovery of a four-neutron particle The best evidence yet that a particle we think shouldn't exist actually does.

What is the Lepton Number? An example of leptons involved in particle decay is the decay of a neutron. Neutrons are stable when bonded to other neutrons and protons in atomic nuclei, but when they ...

Two methods of measuring the neutron's longevity give different answers, creating uncertainty in cosmological models. But no one has a clue what the problem is.

Neutron stars could act as gravitational traps for dark matter, forcing these mysterious particles to collide and annihilate, in the process warming up otherwise cold dead stars.

Gluons mediate the strong force that "glues" together quarks, another type of subatomic particle, to form the protons and neutrons situated at the center of atoms of ordinary matter. While ...

Chadwick repeated their experiments but with the goal of looking for a neutral particle -- one with the same mass as a proton, but with zero charge. His experiments were successful.

Is nature really as strange as quantum theory says—or are there simpler explanations? Neutron measurements at TU Wien prove that it doesn't work without the strange properties of quantum theory.
