The field equations of condensed matter physics are remarkably similar to those of high energy particle physics. As a result, much of the theory of particle physics applies to condensed matter physics as well; in particular, there are a selection of field excitations, called quasi-particles, that can be created and explored. These include:

In high-energy physics, a pseudoscalar meson is a meson with total spin 0 and odd parity (usually notated as J P = 0 −). [1] [a] Pseudoscalar mesons are commonly seen in proton-proton scattering and proton-antiproton annihilation, and include the pion (π), kaon (K), eta (η), and eta prime (η ′) particles, whose masses are known with ...
This second-generation particle is the third-most-massive quark, with a mass of 1.27 ± 0.02 GeV/c 2 as measured in 2022, and a charge of + 2 / 3 e. The existence of the charm quark was first predicted by James Bjorken and Sheldon Glashow in 1964, [ 1 ] [ 2 ] [ 3 ] and in 1970, Glashow, John Iliopoulos , and Luciano Maiani showed how ...

A list of particle accelerators used for particle physics experiments. Some early particle accelerators that more properly did nuclear physics, but existed prior to the separation of particle physics from that field, are also included. Although a modern accelerator complex usually has several stages of accelerators, only accelerators whose ...
Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons , while the study of combination of protons and neutrons is called nuclear physics .
