Current Research Interests

The underlying assumption of scientific thinking is that the behavior of a system can be understood, to a large extent, by the knowledge of its constituents and the interaction between them. Consequently, the study of the smallest particle in nature has a special role - it can 'explain' everything.

The tiniest particles known to mankind are the subject matter of High Energy Physics. During the last 35 years a model which describes with unprecedented success the world of these miniscule entities and their relation was built. The model was put to numerous tests and survived all of them without revealing a hint of a problem. Yet, some of the model's predictions are not yet experimentally confirmed (e.g. the existence of the Higgs boson) and some theoretical considerations indicate that something completely new must be 'just around the corner' (e.g. supersymmetry).

The search for the missing Higgs boson and the search for the expected deviations from the model predictions have been the subject of my work in the last few years. This work will reach a crucial stage in 2007 when the Large Hadron Collider (LHC) will start operating and the ATLAS detector will initiate its data collection stage. The Higgs boson should be discovered by ATLAS in a few years. If not we will have to reexamine the whole theory of the field. Supersymmetry is likely to be discovered and maybe a solution to the dark matter puzzle will also emerge.
