"An Excursion to the Shortest Distance Scales Explored by Humans: Elementary Particles at Work"
11/18/2013Special guest in our Physics Colloquium: Prof. Dr. Andrzej Buras (Technische Universität München, Elementarteilchenphysik)
Abstract:
After a description of our knowledge of short distance scales down to the resolution of 10^18 m and a short summary of the recend Higgs discovery, I will list the most important open questions in elementary particle physics which make us believe that new forces and new particles must exist at scales as short as 10^19 m - 10^21 m. I will explain how such a high resolution of short distance scales can be achieved with the help of very rare decays of mesons (bound states of quarks) and leptons that are governed by quantum fluctuations.
