On 11 August 2025, the Advances in Quantum Field Theory international conference (AQFT-2025) started at the Bogoliubov Laboratory of Theoretical Physics. More than 100 theoretical physicists from Russia, Germany, Vietnam, France, and the United Kingdom gathered to discuss the key issues of modern quantum field theory and its applications, including quantum gravity, holography, supersymmetric field theory, and the modern methods of calculating Feynman diagrams.

In his welcome remarks, BLTP JINR Director Dmitry Kazakov emphasised the importance of quantum field theory (QFT) to Dubna theorists and highlighted the great contribution of the founding fathers of the Joint Institute, Nikolay Bogoliubov and Dmitry Blokhintsev, to research in this field. “Quantum field theory has been successfully developing for over 50 years,” he noted. “This event carries on the tradition of international conferences on QFT, which previously took place in Tomsk and Dubna, bringing together leading scientists and young specialists”.

The plenary session started with a lecture on the topical issues of supersymmetric theories by a chief researcher at the Laboratory of Theoretical Physics at JINR Ioseph Buchbinder. A leading researcher at the Lebedev Physical Institute of the Russian Academy of Sciences Andrei Barvinsky spoke about the Schwinger–DeWitt expansion and the specifics of its application to QFT and quantum gravity. Dmitry Kazakov made a presentation on non-renormalisable interactions. A chief researcher at the Budker Institute of Nuclear Physics Victor Fadin gave a talk on the research of the factorisation of infrared singularities and the application of the Steinmann relations. A BLTP JINR chief researcher Mikhail Ivanov spoke about the progress in heavy quark physics in the covariant quark model, taking into account their confinement.

The AQFT-2025 programme includes more than 70 presentations. The key topics for discussions will be:

• quantum gauge field theory,
• supersymmetric field theory,
• quantum field theory in curved spacetime,
• quantum gravity,
• higher spin theory,
• nonperturbative methods in quantum field theory,
• multiloop calculations,
• string/brane theory and AdS/CFT correspondence.

The Advances in Quantum Field Theory international conference (AQFT-2025) will last for five days and finish on 15 August. The event’s programme is available via the link. The working languages are English and Russian.

Live broadcast is available on the website of the Laboratory of Theoretical Physics at JINR.
