$J/\psi$ reconstruction in the dimuon decay channel with the CBM experiment for pAu collisions at 30 GeV

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.
