The 26th Baikal International Summer School on Physics of Elementary Particles and Astrophysics was held in the village of Bolshie Koty, Irkutsk Region, at the Baikal Biological Station of Irkutsk State University (ISU) from 11 to 18 July 2026. The Joint Institute for Nuclear Research and Irkutsk State University are organizers of the school. For the second consecutive year, the school has received sponsorship from the Autonomous Non-Profit Organization "Scientific and Methodological Center 'Teach-in'" prov
Today was the last day of the 26th Baikal International Summer School, the day when the participants come back home with new knowledge, new friends and new memories; with their bags heavy with not only souvenirs, but also overwhelming emotions; with notebooks full of lecture summaries and ideas; with a poignant feeling that seems to be the beginning, not the end…

Today was the last lecture day. In the morning Maxim Barkov (INASAN) told “How to make jets fast, powerful and variable”, and Elena Nokhrina told about “Magnetic fields in AGN jets”. Two parts of the lecture “Radiation and particle acceleration processes in relativistic outflows” were delivered by Evgeny Derishev (IAP RAS) before and after lunch.
Before lunch, School participants continued with three lectures, the first parts of which were held yesterday: "Gravity, Black Holes and all that" by Emil T. Akhmedov (MIPT, ITEP), "Stars and New Physics" by Sergey Troitsky (INR RAS), and "UHE Neutrino Telescopes" by Grigory Safronov (INR RAS). After lunch, a lecture "Vortex states" was given by Dmitry Karlovets (ITMO University). The students together with their mentors are continuing to work on group projects.

In the morning, the first parts of lectures "Gravity, Black Holes and all that" by Emil T. Akhmedov (MIPT, ITEP), "Stars and New Physics" by Sergey Troitsky (INR RAS), and "UHE Neutrino Telescopes" by Grigory Safronov (INR RAS) were delievered.
The lecture day began with the first part of "Simulation Software" by Andrey Sheshukov (DLNP JINR) and continued with discussions on the prospects of neutrino physics with Liangjian Wen (IHEP) and dark matter with Junting Huang (SJTU). After lunch, Andrey Sheshukov delivered the second part of the lecture on simulation.
Today, the lectures "Introduction to Particle Physics" by Dmitry Naumov (JINR) and "Origin of neutrino mass and mixing" by Zhi-zhong Xing (IHEP, China) continued. The discussion of the prospects of neutrino physics with Liangjian Wen (IHEP, China) and dark matter with Junting Huang (SJTU, China) began.
Today the first lectures, student presentations, questions, and discussions took place. Dmitry Naumov (DLNP, JINR) opened the school with the first part of a lecture titled "Introduction to Particle Physics". Zhi-zhong Xing (IHEP, China) then took the floor with a lecture on "Origin of neutrino mass and mixing (Part I)", followed by Dmitry Gorbunov (INR RAS), who delivered two consecutive lectures on cosmology.
Today, the 26th Baikal International Summer School on Physics of Elementary Particles and Astrophysics began its work. The school will be taking place in the village of Bolshie Koty, Irkutsk Region, at the Baikal Biological Station of Irkutsk State University (ISU) until 18 July 2026.

The seventh issue of the international electronic scientific journal Natural Science Review has published an article by A. R. Didenko, I. V. Eletskikh, and A. O. Gridin, researchers at the Laboratory of Nuclear Problems, titled "Classification of muon tracks from charmonium decays and pion tracks in the model of the SPD detector using neural networks".
The 63rd and 64th meetings of the Programme Advisory Committee on Nuclear and Particle Physics. The staff members of the Laboratory of Nuclear Problems presented the reports on work done and proposals for the extension of the projects. Young DLNP scientists presented their posters.
The International School of Subnuclear Physics was held in Erice, Italy, from 14 to 23 June 2026. This year 11 people presented Russia, among which there were four JINR staff members. Based on the results of the competitions held annually at the school, Aleksandra Ivanova, a trainee researcher at the DLNP Department of Nuclear Physics, received a diploma for the best experimental poster and the Bruno Pontecorvo Diploma as the school's best student.
