Neutrino Oscillation Parameters in a Two-loop Neutrino Mass Model with Leptoquarks

We analyze a neutrino mass model in which neutrino masses arise radiatively at two-loop level with leptoquarks exchange. This model is known for its ability to explain the smallness of neutrino mass with TeV scale leptoquarks and to predict the hierarchy of neutrino mass, thanks to the charged-fermion masses entering the loop. In this article, we focus on parameter space of neutrino mass matrix where the quark masses of the second generation play a significant role. We discuss the predictions of this model, in particular, its compatibility with the current neutrino oscillation data. The consequences of this model on leptoquark decay will also be discussed.
