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 ...

Protons may be intrinsically charming. The subatomic particles are a mash-up of three lighter particles called quarks: two of the type known as up quarks and one down quark. But physicists have ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

Scientists have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...

Mirror magic: The "cores" of the exotic nuclei oxygen-22 and silicon-22 both resemble that of oxygen-16, with eight protons and eight neutrons. The neutron-rich oxygen isotope contains an additional ...

In life, sometimes a small change can make a huge difference. The same goes for physics. A new study was recently published in Physical Review Letters from the Helmholtz Institute for Radiation and ...

Protons have more quantum innards than we previously knew, transforming our view of these particles that sit at the heart of every atom. Researchers have long known that protons are made up of smaller ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators have a new way to use data from high-energy particle smashups to peer inside protons. Their ...
