- 1MuonThe 'heavy electron'. A lepton particle that's negatively charged and has a mass 200 times heavier than an electron.
- 2PionA pi meson (can be negative, neutral or positive). Rest mass greater than muon bus smaller than a proton.
- 3KaonA K meson (can be negatively Neutral or positive). Rest mass greater than a pion bus still smaller than a proton.
- 4MesonsHadron consisting of a quark and an anti-quark.
- 5HadronParticles that can interact through the strong nuclear force.
- 6LeptonParticles that can't interact through the strong nuclear force. They interact through the weak nuclear force. And in the case of muons, electrons and their antiparticles through the electromagnetic force.
- 7QuarksWhat all hadrons are made up of. (only need to know about up, down and strange).
- 8Lepton numberAssigned to every lepton (1+) and anti-lepton (1-). The total lepton number for each branch of the family is always conserved.
- 9V(e)+n ->proton + electron. Cannot be anti-electron and positron.
- 10Muon decays toelectron + anti-neutrino + muon-neutrino
- 11Proton quark combinationuud
- 12Neutron quark combinationudd
- 13Pion (-)d, -u
- 14Pion (+)u, d
- 15Pion (0)u, -u or d, -d, or s, -s
- 16Kaon (+)u, -s
- 17Kaon (-)s, -u
- 18Kaon (0)d, -s or s, -d for the anti K(o)
- 19Conservation rulesConservation of energy, momentum, charge, baryon and lepton number all apply for all particle interactions. Conservation of strangeness applies for strong interaction only.
