text: The charged leptons are all negative particles, their antiparticles are positively charged (for example, the antiparticle of the electron, e-, is a positron, e+).
text: The opposite is also true: the antiparticle of the positron is the electron.
text: An electron’s antiparticle is the positron (an anti-electron), while a neutrino has an antineutrino.
text: The antiparticle of an electron is an antielectron, which is almost always called a "positron" for historical reasons.
text: Antimuons, in mirror fashion, most often decay to the corresponding antiparticles: a positron, an electron neutrino, and a muon antineutrino.
