Title:  The Second Mission of Supersymmetry

Host:  Csaba Csaki

Abstract:  In our four-dimensional world supersymmetry is the only extension of the classical Poincaré invariance which laid the foundation of modern physics in the beginning of the 20th century. Supersymmetry was discovered in 1970 –– it was overlooked for decades because its quantum nature. In the next 10 years or so supersymmetry assumed the role of the main framework in which in which new models for natural phenomena and regularities (e.g. the concept of naturalness) were considered. It gave rise to a powerful stream of theoretical phenomenology.

The fact that LHC at CERN produced no evidence for low-energy supersymmetry (and naturalness as well) was a powerful blow. However, despite its absence in experiments the second mission of supersymmetry, which is less known, is highly successful, with remarkable advances occurring on a regular basis. Supersymmetry proved its power and uniqueness for those who address questions in strongly coupled field theories, including Yang-Mills. Some supersymmetry-based exact results obtained in four-dimensions are the main topics of my talk. In the past one could hardly dream that such results are possible.
