Higgs Physics

With the discovery of a Higgs boson at the LHC a new era in particle physics has started. We are interested in elucidating if this new particle is the one predicted by the Standard Model of fundamental interactions or whether it is connected to new physics. The latter would signify new discoveries.

Exotics Physics

The interactions of the known particles are described within the Standard Model, where all particles and forces are accounted for. We take a look beyond this model at unknown matter which deviates from the norm and has "exotic" properties.


We have a high throughput electronics laboratory at the School of Physics. High throughput electronics deals with massive transfer of data at very high rates in challenging environments. This laboratory serves the upgrade needs of the ATLAS detector and other large projects.


The HEP Group is working together with the school of Electrical Information Engineering on the development and deployment of the Large Hadron Collider Computing Grid (LCG) via the South African Nation Grid (SAGrid).


The MAC Project

The Massive Affordable Computing project (MAC) is an exciting new project which involves the development of modular ARM boards designed to be combined into super clusters to provide a cheap alternative for high throughput super computing at extremely high power efficiencies.

Plastic Scintillators

The study of ionising radiation in various grades of plastic scintilators is necessary for radiation-hardness certification. This is an important topic as these plastics are used in the detectors at CERN and elsewhere. Working with industry to produce plastic scintillators in South Africa.
