Resumo:	We analyze the dark matter (DM) puzzle in a class of models with gauge symmetry SU(3)C ⊗ SU(3)L ⊗ U(1)N, taking into account the constraints coming from Planck observations of the DM relic density, direct detection searches with Xenon1T, and indirect detection using Fermi-LAT data. The model has two possible candidates, a fermion and a scalar, which require, to evade the constraints set by Xenon1T and Fermi-LAT, and have relic densities in the range measured by the Planck collaboration, a minimum vacuum expectation value to break the SU(3)L symmetry of 10 and 15 TeV, respectively. In this case, these particles have masses of order 1 TeV, for the fermion, and between 500 and 600 GeV, for the scalar.
