2. Particle Physics
Building blocks of the universe
Things
Interactions

3. Building blocks

4. Things

5. Fundamental things

6. Dirac equation

7. Fundamental interactions

8. Quantum fields

9. Path integrals

10. Gauge symmetry local gauge field  coupling term (force field)
y (possibly a spinor) respects certain symmetry (L invariant)

11. Feynman diagrams

12. QED: Muon g-2
U(1) symmetry

13. QCD: gluon bremsstrahlung
SU(3) symmetry

14. Weak Interactions: weak neutral current

15. Handedness, Flavours Wu 1956 weak eigenstates ≠ energy eigenstates
??? the lepton sector ???
weak interaction left-handed
??? the neutrino story ???

16. Electroweak Unification
SU(2)xU(1) → spontaneous → weak + e/m
symmetry symmetry breaking (Z0, W±, γ)
(massless (Higgs-Kibble mechanism)
bosons) ↑
Higgs field H

17. Grand Unified Theories

18. Standard Model

19. Gravitation
General Relativity ↑
Equivalence principle
local SR

20. Standard Cosmology

21. Inflationary Big Bang
age ~ length scale ~ radiation frequency ~ energy ~ temperature

22. Contemporary puzzles Dark matter Dark energy SUSY?
Quantum gravity, TOE
SM structure
Spacetime structure; “particles”
etc
