Strong thermal Leptogenesis: an exploded view of the low energy neutrino   parameters in the SO(10)-inspired model
  Leptogenesis is an attractive scenario in which neutrino masses and baryon asymmetry of the Universe are explained together under a minimal set of assumptions.   After formulating the problem of initial conditions and introducing the strong thermal leptogenesis conditions as solution, we show that, within the framework provided by the \soten~model of leptogenesis, the latter lead to a set of testable predictions on the same neutrino parameters currently under experimental investigations.   The emerging scenario selects the normal ordering of the neutrino mass pattern, a large value for the reactor mixing angle, $2\deg \lesssim \theta_{13} \lesssim 20\deg$, as well as a non maximal atmospheric mixing angle, $16\deg \lesssim \theta_{23} \lesssim 41\deg$, and favours negative values for the Dirac phase \delta. The signature of the proposed strong thermal \soten~solutions is in the relation obtained between the effective Majorana mass and the lightest neutrino mass: $m_{ee} \approx 0.8 \, m_1 \approx 15 $ meV.
