High Energy Physics
High-energy physics involves research in fundamental physics, which means experimental and phenomenological investigations into uncharted regions of physics beyond the explored smallest and largest scales.
The research in high energy physics concerns the smallest building blocks of nature and their interactions using sophisticated experiments such as the ATLAS detector at CERN’s Large Hadron Collider in Geneva or the IceCube Neutrino Observatory, a massive neutrino telescope built deep into the ice cap of the South Pole. To test and interpret experimental and observational results we also develop new theoretical models both within and beyond the Standard Model.
Experimental Collider Physics
The experimental collider physics group explores elementary particles and fundamental forces in nature using data from the ATLAS experiment at CERN’s Large Hadron Collider (LHC). The main activities of the group are development of instrumentation, data collection, and physics analysis of the collision data; as well as the design and development of future colliders, namely the Future Circular Collider (FCC) at CERN.
Astroparticle Physics
Astroparticle physics (sometimes called particle astrophysics) is an emergent field of research on the border between particle physics, astrophysics and cosmology. The theoretical branch of this field explores issues relating to the evolution of the cosmos, gravity, dark matter and dark energy, connecting the domain of particle physics with astrophysics and cosmology.
Theoretical Particle Physics
The research in theoretical physics focuses on theoretical physics research in elementary particle physics and astroparticle physics and establish the connection between abstract particle physics theories and reality by making predictions for experiments.
Accelerator Physics
Accelerator physics deals with the physics of charged particle beams and the design, construction, operation, and optimization of particle accelerators.
Grid Computing
The Grid Computing activities at Uppsala University dates back to the creation of the NorduGrid project in 2001. This project was initiated by high energy physicists in the Nordic Countries who wanted to create a computing infrastructure in the region suitable for the computing needs of the experiments at the Large Hadron Collider. In order to achieve this goal collaborations were started with scientists from other scientific fields with a similar interest in computing capabilities. The outcome of this project was a middleware suite that has since become known as the Advanced Resource Connector (ARC).
