TL;DR
The paper articulates Bulgaria's position on the European Strategy for Particle Physics, emphasizing sustained leadership through HL-LHC involvement, neutrino CP studies via the phase $\delta_{CP}$, and engagement with smaller-scale facilities. It details concrete roles in CMS, ALICE, ESSnuSB, SND@LHC, ISOLDE, PADME, and MAGIC/CTA, plus detector R&D and software development. It also highlights the need for robust computing and theory, including access to EuroHPC and advanced ML-informed analyses and non-perturbative QCD tools. Finally, it advocates targeted actions like satellite laboratories and local infrastructure to mitigate brain drain, train the next generation, and ensure long-term European leadership in subatomic physics.
Abstract
The present document summarizes the view and the vision of the Bulgarian subatomic physics scientific community for the development of the field of subatomic physics from the Bulgarian national perspective. It outlines the present activities and the strengths and weaknesses of the research field, together with the interests of the community for the future development of the technological and scientific landscape.
