Subatomic Physics
The study of forces and interactions between
particles

• Strong interactions nuclei ? gluons
• Electromagnetism electrons ? photons
• Weak interactions radioactivity ? W, W-, Z0
• Gravitation galaxies ? graviton

Glashow, Weinberg and Salam The Standard Model
of fundamental particles and interactions
One single theoretical model (Quantum Field
Theory) that describes strong, weak and
electromagnetic interactions

Grand Unification
Unification of forces and interactions Search
for a Super Symmetry
Are we able to include gravity ? Or Can we
quantise space-time ?
Are we able to find a direct relation between
our macroscopic and microscopic world ?
