1. Basics for Nuclear Particle Physics
Before starting…

2. What are fundamental particles?
Elementary particles
Providing the mass
6 leptons (light ones)
6 quarks
Gauge particles
Mediator of forces
4 particles (forces)

3. Twelve Elementary Particles
Leptons
Quarks

4. Gauge Particles (mediator of forces)

5. Other Classification

6. Comparison of the Force Scale
Gravitational force  10-40
Weak force  10-7
Electromagnetic force  10-3
Strong force  1

7. Grand Unification Scheme
To explain forces in terms of exchanging particles
Each coupling constant (related to a specific force) converges
to one value.

8. Unit Systems SI (MKS) units Atomic units Nuclear units
Meters, kilograms, seconds, etc. (macroscopic)
Atomic units
me =1, a.u., etc. (electron base)
Nuclear units
fermis, MeV, etc (nucleon base)

9. Properties of Nuclear Unit System
1 eV = 10-19 J
The energy which one electron can obtain from 1 volt potential difference
The key factor of this unit system
c = [MeVfermi]
Example: electric potential energy

10. Feynman Diagrams
But the diagram does not display its coordinate.
