Elementary particle physics — Then and now

Few-body Physics – Then and Now

A summary of the XIVth International Conference on Few-body Problems In Physics is given, with an emphasis on the important problems solved recently and the prognosis for the future of the field. Personal remarks and “homework” problem assignments are made.

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...

EPS—Then and Now

"Slime" played a brief and spectacular role in the 19th century founded by the theory of primordial slime by Ernst Haeckel. However, that substance was never found and eventually abandoned. Further scientific attention slowly began in the 1930s referring to slime as a microbial product and then was inspired by "How bacteria stick" by Costerton et al. in 1978, and the matrix material was conside...
