Introduction  \nSignificant developments have been applied during the last decades in the field of High Energy Physics (HEP) experiments, including computing technologies. Searches for New Physics phenomena, being an expansion of the so-called Standard Model, i.e. current incomplete theoretical knowledge about the basic behavior of the fundamental constituents of nature and the interactions between them, lead to experimental studies carried out at ever increasing energies. The number of particles created by the interaction of two particles (collision event) is generally increasing with the collision energy. As a consequence a huge number of charged particles have to be reconstructed ([e.g. in](e.g. in) proton-proton collisions), resulting in much more complex event patterns. A typical event in proton-proton collision showing the tracks of multiple particles passing through the detector is presented in Fig. 1, where the particles leave energy deposits (hits) in consecutive detector layers, being a basis for further track reconstruction. In order to enable the search for rare interesting collision events immersed in a huge background of events exhibiting well-known physics, the data rates related to the detector luminosity 1 have increased enormously (e.g. , 40 MHz readout rate in LHC) . It has to be reduced online by more than five orders of magnitude before the information from an event is written on mass storage for further analysis.  \nFigure 1 . Example of an event in High Energy Physics experiment, showing tracks of multiple particles passing through the detector [31] .  \nThis paper aims to review the machine learning based approach applied in crucial stages of the data analysis process in HEP experiments, i.e. the procedure to determine basic kinematic parameters of charged particles at their point of production and the procedure to establish the location of these production points. They are commonly called track and vertex reconstruction. High density of tracks in a single  \n1 Luminosity translates to the number of collisions per second and it is related to track density.  \ncollision event (detector occupancy) in operating and planned high-energy physics experiments results in a large combinatorics of hits in the event pattern recognition. Therefore, a novel machine learning based event reconstruction algorithms have been developed and tested within a framework of the MUonE experiment [21] in order to maximize the statistical power of the final physics measurement. The results of the DNN based algorithm are comparable to the classical reconstruction, allowing not only to reduce execution time of the pattern recognition phase, but also to improve the precision and efficiency of the track and vertex reconstruction.  \n2.
