Scotogenic dark matter and single-zero textures of the neutrino mass matrix

The scotogenic model can simultaneously account for the presence of dark matter and the origin of neutrino masses. We assume that the flavor neutrino mass matrix has one zero element and Yukawa matrix elements are real in the scotogenic model. It turns out that only one pattern of the flavor neutrino mass matrix in the one-zero-texture scheme within the scotogenic model is viable with the observed neutrino oscillation data, the relic abundance of dark matter, and the upper limit of the branching ratio of the $\ensuremath{\mu}\ensuremath{\rightarrow}e\ensuremath{\gamma}$ process.
