Description
The dark photon, $A′$, the dark Higgs boson, $h′$, and the light vector gauge boson, $\omega'$, are hypothetical constituents
featured in a number of recently proposed Dark Sector Models. We will present a search for
these particles in the so-called Higgs-strahlung, radiative, and neutral $D-$meson decay channels. Using the data set collected,
by the Belle experiment,
we present our results for the prompt decay and displaced vertex decay hypothesis when allowed.
