      abstract     = {The CBM experiment at FAIR aims to explore the QCD phase
                      diagram at high net baryon density and moderate temperature
                      by colliding heavy nuclei at an energy range of 4–12 AGeV.
                      The Muon Chamber (MuCh) detector at CBM is dedicatedly
                      designed to detect muon pairs originating at different
                      stages of heavy ion collisions. MuCh consists of absorber
                      segments and detector layers positioned in between the
                      absorber pairs to facilitate a momentum dependent track
                      identification in high particle density environment upto an
                      interaction rate 10 MHz. Gas Electron Multiplier (GEM)
                      chambers are used in the first two stations of MuCh. Two
                      prototype real size GEM detectors called mMuCh setup have
                      been installed in the mCBM (mini CBM) experiment using beams
                      from SIS18 at GSI, Germany. This mCBM is a part of FAIR
                      phase-0 program where a pre-series production of CBM
                      detector systems are being tested with their triggerless
                      streaming readout chain before final CBM production. In the
                      mCBM campaign 2020, data for mMuCh along with other sub
                      detectors have been collected for the Pb+Au collisions at
                      Ebeam = 1.06 AGeV upto an intensity of $\(10^{8}\)/spill$
                      and with different Au target thicknesses. In this work, we
                      will present the performance of mMuCh chambers in terms of
                      the linearity of the response of the mMuCh detectors with
                      beam intensity and its time and spatial correlations with
                      other sub detectors. Three layers of the time of flight
                      (TOF) detectors have been used to form the tracks in the
                      data. After employing a time based event reconstruction and
                      tracking on the mCBM data we have studied the GEM
                      performance in terms of the degree of spatial correlations
                      by constructing residual distributions between reconstructed
                      GEM hits and projected reconstructed tracks at the GEM
                      plane. After re-aligning the detectors positions we tried to
                      estimate GEM detector efficiency and studied its dependence
                      with GEM HV and velocity $(\(\beta$ $\))$ of traversing
                      tracks in mCBM. We acknowledge the help extended by our
                      colleagues at GSI during the data taking},
