Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

Experimental particle physics is the practical investigation of the fundamental components of matter and radiation. A crucial tool in the arsenal of the experimental particle physicist is the particle ...

When a material is heated or cooled, two changes may happen to the particles within the material: The number of particles does not change during a change of state, only their spacing and arrangement.
