atomic theory n. The physical theory of the composition of matter stating that common materials are composed of molecules, which are composed of atoms, which are composed of nuclei and electrons. It holds that the properties of composite entities, such as their structure and behavior, arise from...

The discovery of the J/psi shed new light on quarks and their interactions. It provided support for the theory that there existed a fourth quark, called the charmed quark, in addition to those predicted by early quark models (i.e., the up, down, and strange quarks). See also meson....
…include all of the elementary particles and other things that are postulated in fundamental physical theory—perhaps even continuous fields and points of space-time. Inasmuch as some cosmologists even try to define the elementary particles themselves in terms of the curvature of space-time, there ...
So a total of forty parameters are required for eight super-ellipsoids in theory. But for the poly-superellipsoid particle, the parameters used for each sub-particle have some limitations because the surface of the composite particle needs to be continuous and smooth. To ensure the continuity of...

Graviton is a yet-to-be-discovered elementary particle that is well-known in the realm of quantum gravity. The existence of gravitons could fill critical gaps between quantum mechanics and Einstein's theory of general relativity, making a vital contribution to modern physics, and studying graviton...
