The Large Hadron Collider (LHC) has begun its first-ever collisions of oxygen ions, in the latest attempt to understand the ...

Up quarks have a +2/3 charge, and down quarks have a -1/3 charge. If you add and subtract those fractions, you get the +1 charge of a proton. Valence quarks get lots of attention.

This process, called fragmentation, gives physicists clues about how quarks behave when they’re released from the tight grip of the strong nuclear force. Now here’s where the symmetry jumps in.

The quarks that give it charge aren't hanging out with the gluons that provide mass. John Timmer – Apr 3, 2023 4:30 pm | 116 The Jefferson Lab particle accelerator, where the work took place.

Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces, and pressures inside a subatomic particle for the first time.

Quarks are elementary particles that are the building blocks of all visible matter in the universe. ... Quantum numbers, like strangeness, charge and spin, have to be conserved.

The theory describes quarks as being roped together by force-carrying particles called gluons. Each quark and each gluon has one of three types of “color” charge, labeled red, green and blue; these ...

A Massachusetts jury found Karen Read not guilty of the most serious charges and guilty on a lesser charge related to the 2022 death of her Boston police officer boyfriend John O’Keefe, ending a ...

As quarks rain down on the earth, the British scientists suggest in their Nature article, those with a negative charge combine with oxygen in the ocean to form fractionally charged quark-oxygen atoms.

A collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of 'up' and 'down' quarks within protons. The ...

We can understand things like its mass, its charge and its spin, which is kind of the esoteric aspect of a proton, but that’s another thing we can do with this camera. Feltman: Cool.
