Pair production and annihilation when a particle and its corresponding antiparticle meet they annihilate one another these annihilations do not occur in a purely random way however they must obey 3 rules the conservation of energy the conservation of momentum and the conservation of charge . Pair production and annihilation definition pair production is the creation of an elementary particle and its antiparticle for example creating an electron and positron a muon and antimuon or a proton and antiproton. Later on researchers also saw pair annihilation the conversion of an electron and positron into pure light pair production and annihilation turned out to be governed by einsteins newly introduced theory of relativity in particular his most famous formula e mc 2 which gives the pure energy equivalent of mass
