WebCosmic rays 20.4. Cosmic rays underground Only muons and neutrinos penetrate to signi cant depths underground. The muons produce tertiary fluxes of photons, electrons, and hadrons. 20.4.1. Muons: As discussed in Section 23.6 of this Review, muons lose energy by ionization and by radiative processes: bremsstrahlung, direct production of e+e− ... WebImage courtesy of Fermilab. The muon is one of the fundamental subatomic particles, the most basic building blocks of the universe as described in the Standard Model of particle physics. Muons are similar to electrons but weigh more than 207 times as much. The muon is part of the lepton group. Leptons are a type of fundamental particle.
