This view of the atomic nucleus changed when James Chadwick ... with one being produced by a gluon radiated by a quark-antiquark pair. Physicists love a particle accelerator, and we have since ...

Scientists from the Institute of Modern Physics (IMP) at the Chinese Academy of Sciences have made a breakthrough in ...

Take the quarks as an example. In addition to the pair of quark types known as "up" and "down," which make up the core of atomic nuclei, there exist two additional quark pairs: "charm" and ...

With the electron, proton, and neutron, scientists thought they had found the smallest atomic building blocks. This changed in 1963 when American physicist Murray Gell-Mann proposed his quark theory.

Olaf Massen is a PhD candidate at the Institute for Gravitational and Subatomic Physics at Utrecht University, regularly works at the CERN particle accelerator and mentors the next generation of ...

This fact means that the proton, as far as anyone knows, does not decay – a basic prerequisite for the stability of atomic matter, and so for our existence. The quark model was devised by ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars are ...

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have proposed a key indicator ...

Scientists have proposed a key indicator that may reveal the emergence of quark-gluon plasma (QGP) by analyzing particle ...
