Particle tracking in modern high-energy physics experiments is a challenging task. Well-proven algorithms are no longer capable of providing satisfactory results in terms of processing throughput due to an enormous amount of data being produced through the detector’s environments. At the same time, Graph Neural Networks (GNN) have shown great potential, namely the GNN approach, which was...
The BESIII experiment is a multi-purpose detector operating at the beams of the electron-positron collider BEPCII in Beijing. Particle tracking is a fundamental part of data analysis for this experiment. The inner part of the BESIII tracker suffers from a strong beam-related background, which significantly reduces tracking efficiency for low-pT tracks and the physics performance of the...
The track recognition process (tracking) plays a key role in the event reconstruction in high energy physics. Our study is devoted to tracking for the inner detector of the BES-III experiment, which has only three cylindrical GEM stations. This means, if a particle is registered only at two out of three stations, then its track in the magnetic field cannot be restored without additional...
An overview of the tuned simulation of the drift chambers in the BM@N experiment is given. The comparison with experimental data is also presented.
The configuration of the basic detectors (Forward Si and GEM), included in the inner tracking system of the BM@N setup, has to be improved in order to be in compliance with requirements of the forthcoming experimental runs that will be held in 2021-2022. The preliminary estimation of geometric efficiency for the next configurations of tracking detectors is made with simulation procedure based...
The MPI/C++ /Fortran package of computer codes has been developed for high-performance numerical analysis of experimental data on elastic nucleus-nucleus scattering within a microscopic model of optical potential. In the package, a modified DWUCK4 Fortran-code for calculating the physical characteristics of elastic scattering based on a numerical solution of the corresponding Schrödinger...
We present accurate numerical results for the one-dimensional stationary Schrödinger equation in the case of three quantum problems: quantum harmonic oscillator, radial Shrödinger equation for a Hydrogen atom, and a particle penetration through the potential barrier. All of them were solved by the Numerov method with high accuracy and we plot their wave functions using the results of the...
