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

With PDF functions for the atomic nucleus, it is possible to determine experimentally measurable parameters, such as the probability of a specific particle ... Modification of Quark-Gluon ...

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 ...

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 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 ...

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 ...

Along with quantum mechanics, Einstein's special theory of relativity serves as the basis of the Standard Model of particle physics ... that the rate at which top-quark pairs are produced in ...

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 ...

This has a much greater variety of sub-atomic particles. Some of these rarely exist outside of particle accelerators ... of baryon mesons - Made up of a quark and antiquark pair There are six ...
