The upcoming Large Synoptic Survey Telescope (LSST) will observe 18 000deg$^2$ of the Southern sky and is expected to discover thousands of transientsevery night due to its large coverage of the sky and its observing strategy. Inthis work we address the prospects of the LSST in discovering Tidal DisruptionEvents (TDEs) and in probing the supermassive black hole (SMBH) massdistribution in the Universe. We used the LSST simulation framework and definedTDE catalogs on 20 fields of 20.25 deg$^2$ size. TDE properties were defined byrandomly chosen impact factors and SMBH masses drawn from six different massdistributions. Observations of TDEs in 10 years of LSST operations weresimulated by querying the simulated observing strategy database minion_1016.Based on the results of our simulations we estimate that the LSST shoulddiscover between 35 000 and 80 000 TDEs in 10 years of operations, depending onthe assumed SMBH mass distribution. We also find that probing the SMBH massdistribution with TDE observations will not be straightforward due to the factthat TDEs caused by low mass black holes ($10^ 5 M_\odot$) are expected to beless luminous and shorter than TDEs by heavier SMBHs ($> 10^6 M_\odot$), andtherefore will mostly be missed by the irregular LSST cadence minion_1016.
