O. E. Lychagina "Intrinsic energy resolution of liquid argon scintillation signal"

On the seminar the contribution of intrinsic energy resolution (IR) to the total scintillation linewidth for liquid argon (LAr) detectors is estimated. A complete statistical model of the scintillation process is used, accounting for LAr-specific characteristics. This model establishes the fundamental limits of the energy resolution for large-scale LAr detectors used in particle physics experiments.

E. M. Plotnikova "Study of Bose-Einstein correlations in proton-proton interactions at energies 0.9, 7 and 13 TeV in the ATLAS experiment at the Large Hadron Collider"

The report presents the results of a study of two-particle Bose-Einstein correlations in proton-proton collisions at energies 0.9, 7 and 13 TeV in the ATLAS experiment at the LHC. The Bose-Einstein correlation parameters characterizing the source radius and correlation strength are investigated depending on the multiplicity of charged particles (up to 300) and the average transverse momentum of a pair of particles (up to 1.5 GeV).

P. S. Satunin (INR RAS) "The Cosmological Axion Sarov Haloscope (CASH) project: search for dark-matter axions, dark photons and high-frequency gravitational waves beyond the quantum limit"

Firmly established in astrophysical observations, dark matter evades direct detection in experiments. Axions and axion-like particles as well as dark photons are among the leading dark-matter candidates, and numerous attempts to detect them in laboratories have been performed.

A. A. Grinyuk "Astrophysical Research in the TAIGA Experiment"

TAIGA (Tunka Advanced Instrument for cosmic rays and Gamma Astronomy) is an observatory located in the Tunka valley (Buryatia, Russia), near Lake Baikal. It is a hybrid detector complex designed to study the most extreme phenomena in the Universe by detecting ultra-high-energy cosmic rays, primarily gamma rays in the range from ~1 TeV to several PeV.

M. O. Gonchar "JUNO Experiment: Neutrino Oscillations and More"

JUNO is the largest, multipurpose experiment designed to detect, primarily, reactor antineutrinos. The main goal of the experiment is to determine the ordering and squared mass difference of neutrinos, as well as to precisely measure the lepton mixing angle θ₁₂.

A. V. Guskov "The AMBER experiment at CERN"

Quantum Chromodynamics as a theory of the interaction of quarks and gluons is undoubtedly successful and provides a sufficiently reliable description of processes occurring in the interaction of high-energy particles.

A. A. Sidorin "Generator of Directed Monochromatic Positron Beams for Positron Spectroscopy"

The Positron Annihilation Spectroscopy (PAS) method is sensitive to point defects in solids. The pair of gamma quanta produced in the positron-electron annihilation process carries information about the type and concentration of defects smaller than 10 nm at a depth of up to 1 μm (in dense materials) and up to 15 μm (for light materials), depending on the energy of the positrons.

K. E. Smirnov (JSC) “D. V. Efremov Institute of Electrophysical Apparatus”

In JSC “D. V. Efremov Institute of Electrophysical Apparatus” (Saint Petersburg) a design for a new optimized SS-18P cyclotron has been developed. It is intended to produce proton beams with an energy of 18 MeV and a design current of 150 μA. The previously developed cyclotron complex SS-18/9, equipped with an external injection system and an armored electromagnet with a vertical median plane, was taken as a basis.

P. G. Evtoukhovitch "Development and production process of a pilot module for the COMET Phase II straw tracker"

Project COMET is aimed at searching for the $\mu \to e$ conversion strongly suppressed in the frame of extended Standard Model and will be realized in two stages – Phase-I and Phase-II.

S. M. Deyev "New trends in oncotheranostics" (Shemyakin & Ovchinnikov Institute of Bioorganic Chemistry of the Russian Academy of Sciences, Moscow)

A concept for the delivery of anticancer drugs has been proposed, serving as an alternative to existing approaches based on the enhanced permeability and retention (EPR) effect.

Aleksandr Silenko (BLTP JINR) Relativistic quantum-mechanical description of an acceleration of twisted Dirac particles in a uniform electric field

Twisted beams of charged particles have important applications nowadays. The relativistic quantum-mechanical description of a charged Laguerre-Gauss beam accelerated in a uniform electric field has been fulfilled.
