Experimental Particle Physics

Particle physics studies the smallest building blocks of matter and the interactions through which they interact. The word "particle" generally refers to various types of small objects (e.g. protons, gas particles, or even household dust), but particle physics concerns the indivisible constituents of matter, the so-called elementary particles, that exist now and have existed in the early universe, and the fundamental interactions necessary to explain their behaviour and processes at the highest energies.

The experimental particle physics group at KTH is active at the frontline of hadron collider physics and has contributed to the ATLAS experiment  at the Large Hadron Collider at CERN since 1990.

• The scientific focus of the data analysis activities is on measuring the properties of the Higgs boson and searches for physics beyond the standard model, specifically new particles that could explain the dark matter that dominates our universe.

• The group contributes actively to detector instrumentation, from 1990 to the development, construction, commissioning and operation of the electromagnetic calorimeter based on liquid-argon technology, and for the High-Luminosity LHC the group is contributing to the development of the High-Granularity Timing Detector  which will provide picosecond timing measurements.
