The CERN Council’s resolutions following the invasion of Ukraine by the Russian Federation, with the involvement of Belarus, can be found here.
Belarus has physics research centres with a good scientific basis, and is participating in both ATLAS and CMS, and its contribution to the LHC has been especially effective in the framework of the RDMS (Russia and Dubna Member States in CMS) collaboration.
The contribution to CMS through JINR via the construction of the absorber for the Endcap Calorimeter is particularly significant, and in 2003, the MZOR plant obtained the CMS Gold award for this work. The same factory has also produced other equipment for ATLAS and CMS, while the Research Institute for Applied Physical Problems (Minsk) has contributed to the quality control process of the CMS crystals.
Belarus joined the CLIC/CTF3 collaboration at the end of 2014.
An International Cooperation Agreement (ICA) was signed with Belarus in 1994. In June 2022, the CERN Council declared that it intends to terminate CERN’s International Cooperation Agreement with Belarus at its expiration date in 2024. However, the situation will continue to be monitored carefully and the Council stands ready to take any further decision in the light of developments in Ukraine.
