The top quark’s extreme mass makes it decay almost immediately after it is produced. “The top and antitop quarks just have ...

Objects are made of atoms, and atoms are likewise the sum of their parts—electrons, protons, and neutrons. Dive into one of those protons or neutrons, however, and things get weird. Three particles ...

The small but ubiquitous proton serves as a foundation for the bulk of the visible matter in the universe. It abides at the ...

Asymmetry in the proton confounds physicists, but a new discovery may bring back old theories to explain it. Symmetry — displayed in areas ranging from mathematics and art, to living organisms and ...

Protons make up most of the visible universe. Now, in a new study published in the August 18 issue of the journal Nature, scientists find that because of the strange nature of quantum physics, protons ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The internal structure of a proton, with quarks, gluons, and quark spin ...

NEWPORT NEWS, VA – Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy’s Thomas ...

It's an undeniable scientific fact that dark matter must exist in order to explain the full suite of observations we have about the Universe. Despite all that we know about it, however, we have yet to ...

A new precision measurement of the proton's electric polarizability has confirmed an unexplained bump in the data. The proton's electric polarizability shows how susceptible the proton is to ...

Twenty years ago, physicists set out to investigate a mysterious asymmetry in the proton’s interior. Their results, published today, show how antimatter helps stabilize every atom’s core. It often ...
