Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 times ...

Wang Yifang, project manager of the Jiangmen Underground Neutrino Observatory and director of the Institute of High Energy Physics at the Chinese Academy of Sciences, speaks at the observatory in ...

They're tiny, invisible, and travel across the universe. And trillions of them just flew through your body. What are they? Neutrinos ‒ and scientists Wednesday announced the discovery of the most ...

At a lab in Batavia, Illinois, 200 physicists from seven countries have possibly made the biggest scientific discovery in decades. It involves a subatomic particle called a Muon. It's kind of like an ...

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron. Reading time 2 minutes Physicists have placed a new limit on how big the elusive ...

Physicists working with the LHCb experiment at CERN have proven that a subatomic particle can switch into its antiparticle and back again. The researchers were able to prove this using extremely ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

Muons are getting a move on. In a step toward new types of particle physics experiments, scientists cooled and then accelerated a beam of muons. The subatomic particles, heavy cousins of electrons, ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...
