The structure of the proton is under the microscope at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Newport News, Virginia, where a series of ...

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

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 ...

LOS ALAMOS, N.M., February 24, 2021--A complex high-energy nuclear physics experiment, aiming to measure the contributions of antiquarks to the structure of the proton and neutron, has produced ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

A team of researchers are using the Frontera supercomputer at the Texas Advanced Computing Center (TACC) to crack open the proton, a fundamental building block of the atomic nucleus that is used, ...

The whole is equal to the sum of its constituent parts. That's how everything works, from galaxies to planets to cities to molecules to atoms. If you take all the components of any system and look at ...

New data from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) add detail -- and complexity -- to an intriguing puzzle that scientists have been seeking to solve: how the building ...

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 ...
