Welcome to the Webpages of the High Energy Physics Group of the University of Cyprus


The Cyprus High Energy Physics Group (UCY-HEP) was founded in 1992, the same year that the newly founded (legislation 1989) University of Cyprus started its operation. The Physics Department accepted undergraduate students for the first time in 1993. The UCY-HEP Group currently consists of 12 members:

2 Faculty members of the Physics Department,
2 Postdoctoral Research Associates,
4 Research Collaborators (with PhD degrees)
1 Electronics Engineer
3 PhD Students

After a successful participation in the L3 Experiment at LEP, UCY-HEP joined the CMS Experiment at the Large Hadron Collider (LHC) at CERN in 1995. Over a period of 15 years (2005-2009) our group participated in the construction and testing of the CMS Detector, in particular the Electromagnetic Calorimeter and in the consortium for the construction of the Barrel Yoke and the Vacuum Tank of the 4T Superconducting Magnet of the Experiment.
Since 2009, we are working on Monte Carlo simulation of events and on the real data events accumulated by CMS for a variety of interesting channels, such as the Standard Model Higgs, the search for additional Higgs particles under supersymmetric models (MSSM & NMSSM), B-B(bar) oscillations phenomena etc... Members of the Group had been Conveners on the quality of the data received by the Si Central Detector System.
In addition to the CMS Experiment, a few members of the Group also participate in:  

  • a) the KM3NeT neutrino telescope project, one of the ESFRI projects expected to be funded by the European Union, and upon successful construction to be launched in the Mediterranean Sea,
  • b) the CDF Experiment which now finished its data taking at the Fermi National Accelerator Laboratory, USA
  • c) a series of small scale research projects under the umbrella of the ΕΠΕΦ Laboratory studying the possible impact of non-ionizing radiation on human health. 

Faculty members of the UCY-HEP Group teach undergraduate and graduate courses of the corresponding Physics Curricula, as well as supervise students on their final year projects and on their master and PhD degrees work.

The rich spectrum of Physics covered by the members of the UCY-HEP Group can be visited through these Webpages which, besides the Teaching and Research activities of the Group also provide links on other useful electronic addresses (URL’s) and the possibility to contact the UCY-HEP Group, for the purpose of collaborating or studying with the Group.  



The discovery of the Higgs boson at CERN by the CMS and ATLAS Experiments, two of the biggest and most sophisticated experiments ever constructed in the history of mankind, opens a new era in large-scale international scientific collaboration:

The Higgs boson has been for many years the last and possibly the most important cornerstone of the Standard Model in Particle Physics that describes almost all phenomena in the Universe, from times of the order 10-32 sec until today, some 13.8 billion years after the Big Bang. The Higgs boson comes out as a consequence of the mechanism which is responsible for providing mass to all the known fundamental particles of matter in the Universe, as well as to the carriers of the fundamental interactions governing its evolution. 3 out of the 4 known forces (electromagnetism, strong and weak nuclear forces) have been already quantized and unified, whereas the 4th one (gravity) still needs to be understood at the quantum level (hence we talk of quantum gravity) and its carrier (gravitons) to be discovered. The discovery of the Higgs boson is justified to be considered as the biggest discovery of the last 40 years.

A new era consequently opens up, calling for further investigation on models describing the Universe during the miniscule fraction of time (<10-32 sec) after the Big Bang, as well as on symmetries & asymmetries at the small and large scale structures in the Universe and on new scenarios beyond the Standard Model. This is necessary if we want to have a more accurate description of Nature and the physical reality in the extreme realms of the microscopic world at high energies, high velocities and very early times. Models, such as supersymmetry and other scenarios beyond the Standard Model, string theories, compositeness etc. are currently under heavy investigation, both from the theoretical and the experimental points of view.

To achieve our goals in such extreme regimes we must resort to higher energies and higher luminosities at the Large Hadron Collider (LHC), the biggest proton-proton accelerator at CERN which delivers its beams since the end of 2009. Hence, the necessity arises for a technical upgrade of LHC and our subdetectors systems, electronic data acquisition and monitoring systems, so as to handle far more data and extract extremely accurate results.

Indeed, all the developments currently taking place in the CMS Experiment give rise to more accurate and innovative detectors, faster electronics and triggering, more accurate monitoring systems. These new applications, beyond basic physics, certainly also contribute to the benefit of society. History is full of such examples of technological breakthroughs, where fundamental science leads to the creation of new emerging technologies and vice versa. Always investment in fundamental research leads to new opportunities for scientific, technological and economic breakthroughs, and the circle goes on and on…

Provided that sufficient resources in human capital and materials are allocated to research & development, the members of our High Energy Physics Group, in parallel to the advancement of knowledge in the respective fields are eager to work in several important applications, such as:

1. new particle detector technologies, improving the energy and momentum resolutions, which can also be used with significant advantage in the field of Medical Physics for diagnostic and/or therapeutic purposes

2. advanced trigger and data acquisition electronic systems (DAQ) for handling higher volumes of data at a higher rate, utilizing sophisticated software

3. new and more accurate calibration and monitoring systems for particle physics detectors

4. development and running of extensive Monte Carlo events on the Grid network.
