What do we specialise in?

High-energy physics deals with research using the largest accelerators, which use electric and magnetic fields to accelerate and direct streams of particles - beams. These beams can collide with each other, or with a fixed target, and the resulting other particles are registered by specialized detectors. Analysis of the resulting particles provides information about the structure of the basic components of matter and the forces (interactions) between them. High-energy particles that arise naturally - for example, atmospheric neutrinos - are also used.

BP3 scientists deal with questions about the fundamental elements of the world of elementary particles and the Universe, and work on models and analysis of data from various experiments in the context of the study of the Standard Model and the search for so-called new physics (physics beyond the Standard Model).
