Abstract: The investigation of charmonium production is one of the key goals of the CBM experiment. The study of pAu collisions at 30 GeV beam energy is considered a part of the CBM research program and will be performed in the first phase of FAIR with a start version of the CBM detector at SIS-100. Results of $J/\psi$ reconstruction feasibility studies in dimuon channel in proton-nuclear collisions at SIS-100 energies with the use of KFParticle package are presented. Simulated detector concept includes STS and MuCh detector systems. The algorithm allows to reconstruct $J/\psi$ with an efficiency of 27.16% and the signal to the background ratio of 19.4.

Keywords: CBM, elementary particle reconstruction methods, high energy physics.
