Data Analysis

The dream of modern physics - the theory of everything - is not yet realised. Although the modern theory of elementary particles and fields, the Standard Model, describes the results of all particle scattering experiments with high precision, many questions remain open, such as

  • How are all fundamental interactions unified?
  • Why are there three generations of quarks and leptons?
  • Why are there six quark flavours and their mixing?
  • What is dark matter?
  • ...


Various extensions of the Standard Model have been proposed to deal with these issues. Some of these theories would bring a new revolution in physics, if they are confirmed by experiments. Analysing data collected with the ATLAS detector at the LHC, we are looking for the signatures predicted in these theories. Currently we are interested in the supersymmetry between bosons and fermions, and in models with extra dimensions. But before any discovery can be claimed, one has to ensure that no detector effects fake the signals of new physics. Therefore we also perform extensive detector studies. We focus on calibrations of the calorimeters and on understanding of hadronic jets.

Standard Model

The Standard Model (SM) is a theory describing fundamental particles and the interaction between them. These fundamental particles are all fermions, continue...


The theory of Supersymmetry (SUSY) assumes a new symmetry of nature. SUSY predicts for each fermion (matter particle with spin 1/2) a bosonic partner (force particle with integer spin) and vice versa. continue...

Extra Dimensions

Our world can have more than three space dimensions. Additional, so far unseen, dimensions can appear at very small distances, if they are 'compactified'. continue...

Jet Studies

Many signals of new physics at the LHC involve hadronic jets. A jet is created from a scattered quark or gluon due to the confinement. continue...
