What is lepton?

leptons are a family of elemental particles that include electron, Muon, Tau and their associated neutrinos. Like Quarks , which form protons and neutrons in the atomic core, lepton fermion , which means that it has quantum rotations ½. Other basic particles with different spins are called bosons and mediate interactions forces between the fermions. Fermions, composed of lepton and quark, are "meat" of matter, while the bosons are "skeleton".

Compared to quarks, lepton is light. The weight of the electron is 1–1836 atomic mass unit (AMU), approximate weight of hydrogen atom. The weight of the nepton in the hydrogen atom comes from the core. Two more Lepton variants - Muon and Tau - are significantly harder. Tau Lepton weighs almost twice as much as proton. Each has an associated neutrino - electron neutrino, Muon Neutrino and Tau Neutrino. Neutrinos have almost zero weight and without charge and travel near the speed of light.

Electron and other basic leptons have a negative charge, are more stable than neutrinos and can atomic cores of orbit. The electron is the most stable of three and can be found in conventional mass. Muon and Tau are created during experiments with particle accelerator or through the impact of space beam. Each of these six particles has an associated antiparticle of the opposite charge, thereby calling the total number of leptons to 12. These anti -parties are called antielektrons , antimuons and Antitaus .

When the etchings containing systems interact with each other, the total number of leptons tends to be maintained. A rare circumstance in which the number is not maintained is called the chiral anomaly . Sometimes leptons change their type, but it usually requires high energies and heavier leptons are not very stable.
