Module 6 - Chapter 24 - Particle Physics II
Beta Decay
Beta minus
Neutron decays into a proton and an electron and an anti electon neutrino
Mass number and atomic number are conserved, aswell as total charge
Baryon and lepton number are also conserved
Occurs in isotopes with too many neutrons
One of the down quarks becomes an up quark
Beta plus decay
Proton decays into a neutron and a positron and an electron neutrino
Occurs in isotopes with too few neutrons
One of the quarks becomes a down quark
Leptons
Electrons
Muons
Tauons
Neutrinos
Carry no charge and have a tiny mass
Three types: Electron neutrino, muon neutrina and tau neutrino
Interact via the weak force
Hadrons
Six quarks + anti quarks
Up (u) +2e/3
Down (d) -e/3
Anti up (ū) -2e/3
Anti down (d) +e/3
Charm (c) +2e/3
Anti charm -2e/3
Strange (s) -e/3
Anti strange e/3
Top (t) +2e/3
Anti top -2e/3
Bottom (b) -e/3
Anti bottom +e/3
Baryons
Neutron udd (0)
Proton - uud (+1e)
Any hadron with a combination of three quarks
Mesons
Hadrons made with a combination of a quark and anti quark
π+ up + antidown
π0 up + anti up or down + anti down
π- anti up + down
Fundamental particles
Particle with no internal structure and can't be divided into smaller bits
Hadrons - particles and particles that are affected by strong nuclear force, decay by weak nuclear force. any particle containing a quark is a hadron
Leptons - particles and antiparticles that interact via the weak force
