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 ...

The two-dimensional spatial distribution of mass due to gluons in the nucleon (left) and the pion (right), simulated at seven valence pion masses with lattice quantum chromodynamics. Understanding the ...

The subatomic particles are incredibly numerous. About 1,000 neutrinos from stars other than the sun pass through a thumbnail ...

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 ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The bleeding edge of physics lies in a beam of subatomic particles ...

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 ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

The search for dark matter has been largely unsuccessful so far. But now, scientists think they know where to look for it.

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 ...

Since the 1930s, scientists have been using particle accelerators to gain insights into the structure of matter and the laws of physics that govern our world. Today, these accelerators are some of the ...
