Compare and contrast positrons with electrons
http://positrons.ucsd.edu/positron/papers/CSM11.pdf WebElectron–positron annihilation occurs when an electron ( e −) and a positron ( e +, the electron's antiparticle) collide.At low energies, the result of the collision is the annihilation of the electron and positron, and the creation of energetic photons: . e − e + → γ + γ. At high energies, other particles, such as B mesons or the W and Z bosons, can be created.
