Muon lifetime refers to the average time a muon exists before decaying, typically around 2.2 microseconds. This decay process is a key example of weak interaction, providing insights into fundamental particle interactions and the structure of the universe.

Muon decay is a process in which a muon, an unstable subatomic particle, transforms into an electron, a neutrino, and an antineutrino via the weak nuclear force. This decay provides crucial insights into the weak interaction and helps test the Standard Model of particle physics, particularly in understanding lepton universality and neutrino properties.

The weak interaction, one of the four fundamental forces of nature, is responsible for processes like beta decay and neutrino interactions, playing a crucial role in nuclear fusion and stellar phenomena. It is mediated by the exchange of W and Z bosons and is unique in its ability to change the flavor of quarks, thus affecting the composition of atomic nuclei and the universe's matter-antimatter asymmetry.
