  1. 1Name three quarksUp, Down, Strange
  2. 2What is the baryon number of a quark?+1/3
    (antiquarks have a baryon number of -1/3)
  3. 3What is the quark composition of a proton?uud
  4. 4Name the two types of fundamental particle that make up matter.Quarks and leptons
  5. 5What is the quark composition of a neutron?udd
  6. 6Name the two types of hadron.Baryon and meson
  7. 7What are the quark compositions of hadrons and antihadrons?hadron: 3 quarks
    antihadron: 3 antiquarks
  8. 8What is the quark composition of a meson?One quark and one antiquark.
  9. 9Name the antiparticle of an electron.Positron
  10. 10What is the quark composition of an antineutron?1 antiup quark and
    2 antidown quarks
  11. 11'Force carrying' particles are collectively known as what?Bosons
  12. 12What is the charge of i) a muon, ii) an antitau particle?i) muon: -1
    ii) antitau: +1
  13. 13To what class of particle do electrons and neutrinos belong?Leptons
  14. 14What is a particle composed of quarks called?A hadron
  15. 15What interactions can hadrons interact throughAll four, strong and electromagnetic if charged. Tend to decay through weak unless its a proton (because its stable)
  16. 16What interaction do leptons not interact through?Weak interaction
  17. 17During what interaction is strangeness conserved?Strong interaction
    (change by 0,1,-1 in weak)
  18. 18In any reaction, what 3 things are conservedCharge + energy + momentum
    Lepton number
    Baryon number
  19. 19What stable baryon does other baryons eventually decayProton
  20. 20What is the exchange particle for the strong nuclear forcePion
  21. 21What particle decays into pionsKaons
  22. 22What particle decays into a electronPions
  23. 23Through what interactions are strange particles produced and decayProduced - Strong
    Decay - Weak
  24. 24Strange particles are always produced in...Pairs
  25. 25What is the decay of a neutronB- decay
