Research @ DESY Zeuthen Theory Group
Theoretical elementary particle physics is dealing with the laws of
the fundamental forces, like the electromagnetic, the weak and the
strong interaction forces and with the structure of the elementary
particles. The framework of elementary particle theory is quantum
field theory, in particular, the Abelian and non-Abelian gauge
theories. Our research plays a crucial role for the interpretation of
the particle accelerator experiments performed at DESY and
elsewhere. Current activities of the Theory Group at DESY Zeuthen
concern: phenomenology of high energy processes, electroweak theory,
perturbative and non-perturbative Quantum Chromodynamics (QCD).
Calculations are performed analytically as well as with high
performance computers. In particular the non-perturbative
investigation of QCD on a lattice requires enormous computer
resources.
Some selected projects:
Bhabha Scattering
Numerical packages for collider experiments
The data from experiments performed at high energy
colliders have to be confronted with numerical theoretical predictions
in order to gain new insights into Nature.
For this reason, theoretical research results not only in publications
in scientific journals or books, but also in computer codes for the
support of the analysis of experimental data.
Here are some links to projects related to Fortran (c++,...) packages,
which have been created in our group or to which we simply would like to
draw some attention:
Numerical projects
Tools for loop calculations
The numerical predictions often are based on perturbative calculations in the
Standard Model (or in other scenarios), including virtual higher order
quantum corrections.
These perturbative calculations are quite complicated and rely more
and more on computer algebra systems (CAS).
Here are some links to CAS we are using or we simply would like to
draw some attention to:
CAS
Symbolic Summation Techniques (in cooperation with
RISC, Johannes-Kepler University Linz)
Lattice gauge theory
The APE project
