Wherever two quarks of a flavor called 'up' are bound to a flavor called 'down', you'll find a proton. Make it two down quarks and a single up, you'll have yourself a neutron. Describing quark trios ...
A proton has two up quarks and one down quark; a neutron has two down quarks and one up quark. GPDs can be split up by quark flavor. Combining measurements of DVCS on the neutron with previous ...
Researchers seek to answer questions such as how the universe evolved just after the Big Bang from a super-hot plasma of quarks and gluons, how the different elements of the universe were formed, and ...
A new way to detect neutrons Nucleons are made up of smaller particles called quarks and gluons. Physicists don’t yet fully understand how these constituent particles are distributed inside ...
