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