BB2026 workshop on R&D in particle physics

30 Mar 2026, 14:00 → 1 Apr 2026, 17:00 Europe/Zurich

The workshop is organized to strengthen and further develop the collaboration between the high energy physics groups of some of the key research institutions in China and Serbia, such as the University of Belgrade and Beihang University, as well as the IHEP Beijing. 
It will serve as a forum to present current research activities, discuss recent scientific progress, and explore new opportunities for cooperation in both phenomenology and experiment.

The first day will be dedicated to theoretical, phenomenological, and experimental studies of possible quantum properties of space-time, with a particular focus on Lorentz invariance violation and noncommutative space-time effects, and the programme will include invited talks by some of the leading experts in this field.

The second day will focus on broader discussions of future joint high-energy physics research and development, including prospects for cooperation in the context of major future collider programmes, notably the European FCC and the Chinese CEPC, as strategic frameworks for long-term collaborative work.

Overall, the workshop aims to deepen scientific exchange, encourage new collaborative initiatives, and strengthen the long-term partnership between the participating institutions.
