Physicists know from previous experiments that what happens at the nuclear scale to protons and neutrons also affects their ...

When atoms and subatomic particles swirl and crash ... and dissolve into basically soup. That’s quark-gluon plasma. It can be created by smashing atomic nuclei together at very high speeds ...

In a major milestone for particle physics, scientists at CERN’s Large Hadron Collider (LHC) have successfully observed top ...

Without quarks, it’s impossible to imagine an atomic nucleus ... to the other through a process called quark mixing. Even the Standard Model of particle physics doesn’t explain how frequently ...

The Large Hadron Collider Beauty (LHCb) collaboration has observed a type of four-quark particle never seen before ... the strong interaction that binds protons, neutrons and the atomic nuclei that ...

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 ...

There are, however, six different types of quarks which combine in different ways to form other kinds of particle. Those that have been detected so far contain at most, one heavy quark.

This is possible because just as a RHIC collision can kick an energetic quark or gluon free, that interaction can also produce a high energy photon, or particle of light. These direct photons are ...

The centers of neutron stars are expected to reach the highest particle densities in the universe, so it is possible that neutron stars harbor quark matter in their inner cores. Studying the ...

This high-density quark behavior is called color superconductivity. The strength of pairing inside a color superconductor is difficult to calculate, but scientists have long known the strength's ...

When a radioactive atom emits an alpha particle the mass number decreases by four and the atomic number drops by ... involves the conversion of a down quark to an up quark. This changes a neutron ...
