Results of the meetings of the Programme Advisory Committee for Particle and Nuclear Physics
The 64th meeting of the Programme Advisory Committee was held on Monday, 15 June 2026. Deputy Director of the Laboratory of Nuclear Problems at JINR, SPD Co-Spokesperson Alexey Guskov presented a talk on the Spin Physics Detector at the NICA Collider. All the efforts of the international team of scientists and engineers are currently focused on creating the experimental facility and the necessary infrastructure for the experiment’s first phase. Alexey Guskov confirmed that in the coming months, it is planned to conclude a contract for the manufacture of a thousand-tonne magnet yoke, a key element of the detector. Technical documentation for a superconducting magnet is being prepared together with colleagues from the Budker Institute of Nuclear Physics. In addition, there is progress in the development of infrastructure for the SPD cryogenic system, along with detector subsystems. The manufactured prototypes of beam-beam counters and zero degree calorimeters will be installed at the SPD interaction point during the next NICA Collider run. “This will not just be detector tests for us. This will be an opportunity to study background conditions, estimate luminosity, and provide JINR accelerators with a reliable tool for observing collisions,” Alexey Guskov emphasised.
A significant part of the 64th PAC PP meeting programme was devoted to reviewing reports on the participation of JINR research teams in external projects, the implementation period of which ends in 2026. After hearing and comprehensively discussing talks by the scientific group representatives, the committee members highly appreciated the results achieved and the significant contribution of the Joint Institute’s specialists. PAC members recommended prolonging JINR’s participation in the international NA61/SHINE, NA64, STAR, AMBER, JUNO, and TAIGA Experiments, as well as continuing work on the “Methods, algorithms, and software for modelling physical systems, mathematical processing, and analysis of experimental data” project.
Furthermore, Ivan Eletskikh, the head of the Sector 6 of Hadron Structure and Spectroscopy of the Department of Colliding Beams, told about scientific results and contribution of the JINR group in the ATLAS experiment at the CERN Large Hadron Collider.
Upon completion of the meeting young DLNP scientists presented their posters on research topics in the field of particle physics:
Maria Dima “Ultra-Fast Determination of the Primary Vertex at SPD”
Prokhor Egorov “Amplitude analysis of ψ(3686) decays into π⁰π⁰ system”
Natalia Kovyazina “Full-cycle production complex for Micromegas detectors”
The next meeting of the Programme Advisory Committee was devoted to nuclear physics and was held on 18–19 June 2026. Within the meeting Dmitry Naumov, Deputy Director of the Laboratory of Nuclear Problems, presented a report about the status and prospects of the JINR Neutrino Programme.
