Abstract. Muons are one of the twelve fundamental particle types of matter, having relatively long free-particle lifetime. A muon decays into three other light particles (leptons) through action of the “weak” force, transmitted by the so-called “heavy photons” - bosons W+/W-.

Why are muons so unstable?
A muon is relatively unstable, with a lifetime of only 2.2 microseconds before it decays by the weak force into an electron and two kinds of neutrinos. Because muons are charged, before decaying they lose energy by displacing electrons from atoms (ionization).
Why do particles decay?
Because there are various forces that let particles to interchange among themselves. These forces not only let particles decay but can interact in different ways to make more exotic particles. One such process is top quark production from electron-positron scattering.
How does a muon decay into an electron?
Muons may only decay to electrons -the only particles lighter than muons which carry the same electric charge- and they do so by means of the exchange of a W boson, the carrier of the electroweak charged-current interaction.

Why do protons decay into neutrons?
A free proton cannot decay into a neutron - you need a proton in a (rather specific) nucleus. The "missing" energy comes from the binding energy of the nucleus - the binding energy for the nucleus with one extra proton happens to be larger than the same nucleus with one extra neutron.
