1. More Particles

   • Muon
     • Negativly charged particle with a rest mass over 200x that of an electron
     • A muon decays into an electron and an antineutrino. An antimuon decays into a positron and a neutrino
   • Pion
     • π meson a particle that can be positively charged, negatively charged or neutral, and has a rest mass greater than a muon but less than a proton
     • A charged Pion can decay into a muon and an antineutrino or an antimuon and a neutrino. Neutral Pions decay into high energy photons
   • Kaon
     • K meson which can also be positively charged, negatively charged or neutral, and has a rest mass greater than a pion but still less that a proton
     • A Kaon can decay into pions, or a muon and an antineutrino, or and antimuon and a neutrino
