Hi, Could someone tell me please what is the scientific consensus(or some interesting theories) on why do muons decay and what is the mechanism of it? My understanding of particle decay is based on for example neutron wchich decays because a quark in it flips from down to up. But leptons, if they have no internal structure(that I know of) can't decay this way. So how? Is it because of interaction with some virtual particles? Are there any fairly recent articles about it? Wikipedia only informs they decay via "weak interaction" which doesn't explain a lot. Using my imagination I came up to a possible explanation that there is some intrisic instability in so much mass concentrated in a lepton so when a right mix of virtual particles appear nearby the muon "gets rid" of its energy for their benefit. I wonder what explanation real physicist have?
