Standard model

Question 1

What are fermions?

Answer 1

Particles that make up matter (quarks and leptons)

Question 2

6 quarks

Answer 2

Up, down, top, bottom, strange, charm

Question 3

6 leptons

Answer 3

Electron, tau, muon
Electron neutrino, tau neutrino, muon neutrino

Question 4

What are bosons and what are the 5?

Answer 4

Force mediators responsible for interactions
1. Gluon
2. W+, W-, Z0
3. Photon
4. Higgs boson
5. Graviton (maybe)

Question 5

What is the gluon responsible for?

Answer 5

strong nuclear force (nucleus force)

only between quarks

Question 6

What are the W+, W-, Z0 responsible for

Answer 6

weak nuclear force: b+ and b- decay, quark decay

Question 7

What is a photon responsible for

Answer 7

electromagnetic force: annihilation/creation

Question 8

What is the Higgs boson responsible for

Answer 8

gives matter mass

Question 9

What is conserved during interaction?

Answer 9

Lepton number and Baryon number

Charge

Strangeness (NOT weak nuclear interactions)

Question 10

What is a Baryon?

Answer 10

3 quarks

Question 11

All baryons have a baryon number of what?

Answer 11

1

Question 12

Quarks have a baryon number of what?

Answer 12

1/3

Question 13

Leptons have a baryon number of what?

Answer 13

0

Question 14

Leptons have a lepton number of what?

Answer 14

1

Question 15

Quarks have a lepton number of what?

Answer 15

0

Question 16

What is conserved in an anti-particle compared to its counterpart particle and what is not conserved?

Answer 16

Antiparticles have the same mass

Opposite charge, spin, baryon number

Question 17

What is a meson?

Answer 17

A particle made up of a quark and anti-quark

Question 18

Contrast the force responsible for quarks vs leptons

Answer 18

Quarks: strong nuclear force

Leptons: weak interaction, electromagnetic and gravity. NOT reactive to strong force
