Supersymmetry in Elementary Particle Physics

These lectures give a general introduction to supersymmetry, emphasizing its application to models of elementary particle physics at the 100 GeV energy scale. I discuss the following topics: the construction of supersymmetric Lagrangians with scalars, fermions, and gauge bosons, the structure and mass spectrum of the Minimal Supersymmetric Standard Model (MSSM), the measurement of the parameter...

Evolution of Elementary Particle Physics in the 20th Century

The history of physics from the middle of the 19th century until 2000 is presented. The dominant drive for the development is related to the creation of Quantum Mechanics in the first half of the 20th century. New concepts like the particle-wave duality and the definition of an elementary particle are discussed. The explosion of the number of particles, due to new accelerators, led to the theor...
