MLIT scientists at 15th BM@N collaboration meeting

On 14–16 October 2025, the 15th collaboration meeting of the BM@N experiment took place at the JINR Veksler and Baldin Laboratory of High Energy Physics. Over 130 specialists gathered to discuss the collaboration’s latest achievements and the project’s development strategy for the coming years.

The staff members of the Meshcheryakov Laboratory of Information Technologies actively participate in the BM@N experiment. Six talks were delivered by MLIT specialists at the 15th collaboration meeting. Head of the Distributed Real-Time Systems Sector Igor Alexandrov discussed the status of work being performed jointly with VBLHEP specialists on the design and development of the Data Quality Monitoring (DQM) system for the BM@N experiment. The report covered the objectives of the system’s creation and major design decisions, including the overall architecture, class diagrams, key DQM configuration issues, the database structure, and other design aspects.

It was reported that work on implementing the system had started, in particular, C++ configuration-related classes had been elaborated and uploaded to GIT.

Dmitry Baranov, a researcher in the Sector of the Development of Mathematical Support Based on Large Software Complexes and Data Visualization Tools, presented a report entitled “Generative Adversarial Networks for charge cluster simulation in the GEM detector of the BM@N experiment”. The speaker described the successful development of a model based on a Generative Adversarial Network (GAN) for realistically simulating the response in the GEM detector, as well as plans for further improvements of this model.

Evgeny Alexandrov, a researcher in the Distributed Real-Time Systems Sector, delivered a talk on the current state of geometry and configuration systems and outlined further steps for their enhancement. The results of the work presented were obtained by a team of specialists from MLIT and VBLHEP.

Head of the Sector of Methods for Solving Mathematical Physics Problems Zarif Sharipov summarized in his report entitled “Geometrical alignment of the BM@N STS and GEM detectors in 3 coordinate directions” the work carried out on a method for finding correction parameters for the STS and GEM detectors to enhance the quality and accuracy of the signal received from the detectors.

Igor Pelevanyuk, a researcher in the Distributed Systems Sector, reported on the readiness of the automated data processing mechanism for BM@N Run 9.
As part of his work, he also simulated the automatic launch of tasks and verified the ability to promptly process incoming data on available Tier1 and Tier2 resources even with a two-fold increase in data-taking intensity compared to Run 8.

MLIT researcher Genis Musulmanbekov presented an analysis of the neutron spectrum measured at VBLHEP and reported earlier at a seminar in September. The spectrum’s behavior in the low-energy neutron region, which is not described by model computations, caused a lively discussion at the seminar. In his talk at the collaboration meeting, Genis Musulmanbekov analyzed possible reasons for the discrepancy between the model and the experiment.

Specialists of the Meshcheryakov Laboratory of Information Technologies make a considerable contribution to the development of the BM@N experiment.
