D students & lack of a fellowships scheme § moderate infrastructure § difficulties to activate industry, companies, private sector § brain drain § lack of venture capital companies in Cyprus § lack of flexibility in procedures Established a Strong Group with International Reputation

UCY Working with the UCY-HEP Group HEP 1. Collaboration with CERN and several top-class universities for many years: opportunities to attract high caliber international and Cypriot researchers of the diaspora 2. Some of our talented students already pursue careers abroad Z. Zenonos (Pisa), A. Petrides (Sweden) A. Alekou (Imperial), N. Iracleous (Brussels), V. Chadjivasiliou (Syracuse) 3. Strong commitment in international HEP research 4. Strong expertise in Standard Model Physics and searches for new phenomena 5. Many activities will benefit by increasing funding & manpower and by establishing a Research Fellowships Scheme 6. Extension of Technical Protocols for Cooperation with CERN 7. Joint organization of schools/conferences 8. Potential for developing applications on detectors, electronics, monitoring & control systems, Grid computing, medical physics 28
