Description
Electron-positron particle shower. Particle tracks (moving from bottom to top) showing multiple electron-positron pairs produced from the decay of a high-energy gamma ray photon produced by a neutrino collision. The positron is the anti-particle of the electron, and this photon decay process is called pair-creation. Electrons and positrons are charged particles and form these paired spirals as they curve away from each other in a magnetic field. As they do so, they radiate photons, which in turn produce new electron-positron pairs. This shower of particle creation continues until the energy of the original photon is used up. The region shown here is about 2 meters tall.
