Abstract

One of the main purposes of the SHiP experiment is to shed light on neutrino mass generation mechanisms like the so-called seesaw one. We consider a minimal type-I seesaw neutrino mass mechanism model with two heavy neutral leptons (right-handed or sterile neutrinos) with arbitrary masses. The extremely high active-sterile mixing angle requires a correlation between the phases of the Dirac neutrino couplings. Actual experimental limits on the half-life of neutrinoless double beta decay 0νββ-rate on the active-sterile mixing angle are not significative for SHiP.
