Bernd Jantzen – Science

Research interests

Before joining the IT sector, I was involved in elementary particle physics. This a field of fundamental science where the focus is on the elementary constituents of matter and radiation and the interactions between them, especially at high energies and small distances.

My fields of interest in this domain of physics include:

  • particle physics phenomenology,
  • physics at the Large Hadron Collider (LHC) and the International Linear Collider (ILC),
  • effects of electroweak interactions at high energies, especially the so-called Sudakov logarithms,
  • algebraic methods for multi-loop calculations,
  • asymptotic expansions in the high-energy limit and near production threshold.

Please have a look at my list of publications and at my list of talks.

Physics studies and PhD thesis

I studied physics at the University of Karlsruhe (today Karlsruhe Institute of Technology – KIT) from 1996 to 2002. During this period, I also spent one year (1999–2000) in France, at the Université Joseph Fourier in Grenoble (today Université Grenoble Alpes), where I have obtained the certificate “Maîtrise Physique”. I concluded my undergraduate studies in Karlsruhe in 2002 with a one-year thesis at the Institute for Theoretical Particle Physics and obtained the “Diploma in physics”, which corresponds to a Master Degree.

My scientific work continued at the same institute with a PhD thesis under the supervision of Prof. Dr. Johann H. Kühn. I obtained the PhD in physics (“Dr. rer. nat.”) in 2005 with the thesis “Sudakov-Logarithmen in der elektroschwachen Wechselwirkung” (“Sudakov Logarithms in Electroweak Interactions”).

Postdoc positions at PSI and in Aachen

From August 2005 to September 2008 I worked as a postdoc (scientific assistant) in Switzerland, at the Paul Scherrer Institut (PSI) in Villigen, more precisely in the Theory Group of the Laboratory for Particle Physics.

From October 2008 to March 2013 I was a postdoc at Rheinisch-Westfälische Technische Hochschule Aachen (RWTH Aachen University) in the Institute for Theoretical Particle Physics and Cosmology.
