Head Aushev Volodymyr Ye., Доктор фізико-математичних наук Registration Date 13-02-2026 Organization Taras Shevchenko National University of Kyiv popup.description1 The goal of the project is to measure the interaction cross sections of neutrinos with Ar-40 nuclei. Experimental studies of interactions of neutrinos with nuclei and taking into account the nuclear environment will be connected with the verification of theoretical predictions. popup.description2 The project aims to measure neutrino interaction cross sections on 40Ar nuclei. Experimental studies of neutrino–nucleus interactions, including nuclear medium effects, will be combined with tests of theoretical predictions. The main objectives include Monte Carlo simulation of physical processes in a liquid argon time projection chamber (LArTPC) induced by neutrinos of different flavors; development of 2D/3D track reconstruction and particle identification algorithms, including the use of machine learning methods; calibration of dQ/dx for detector modules; experimental measurements and theoretical calculations of neutrino cross sections; and studies of charged-particle multiplicity in neutrino interactions. Liquid argon TPCs are advanced neutrino detectors capable of precise energy measurement, flavor identification, and 3D reconstruction of secondary particles. To ensure large active mass, they are designed in a modular configuration, where each module operates with a short electron drift distance, moderate voltages, and high spatial resolution. The DUNE experiment implements this technology in its near detector system, with a total of 40 kilotons of liquid argon planned. This enables precise measurements of neutrino cross sections, oscillation parameters, CP violation (with percent-level sensitivity), and advances in studies of neutrino mass ordering, proton decay, and supernova neutrinos. Key challenges of large LArTPCs include high-voltage operation (up to 500 kV), strict argon purity requirements due to electron attachment, and photon detection complexities. A modular design mitigates these risks and supports operation at higher event rates. Proper treatment of nuclear effects further improves the accuracy of neutrino interaction analysis.
