Researchers perform a global analysis of lead-lead collisions, finding that agreement with the reaction rate requires a much smaller nucleus. Low-energy experiments find a nucleon size of around 0.5 ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet ...
