Definition that contains subatomic particle
- string (cosmology) a hypothetical one-dimensional subatomic particle having a concentration of energy and the dynamic properties of a flexible loop
- wimp a hypothetical subatomic particle of large mass that interacts weakly with ordinary matter through gravitation; postulated as a constituent of the dark matter of the universe
- powell English physicist who discovered the pion (the first known meson) which is a subatomic particle involved in holding the nucleus together (1903-1969)

- high-energy physics the branch of physics that studies subatomic particles and their interactions
- particulate radiation a stream of atomic or subatomic particles that may be charged positively (e.g. alpha particles) or negatively (e.g. beta particles) or not at all (e.g. neutrons)
- corpuscular radiation a stream of atomic or subatomic particles that may be charged positively (e.g. alpha particles) or negatively (e.g. beta particles) or not at all (e.g. neutrons)
