Abstract
We study the light neutrino mass matrix in the Extended Double Seesaw Model (EDSM), and as a result we get its general form. Also we demonstrate that conventional type-I and double seesaw mechanisms can be regarded as two special cases. We analyze the structure of the 9×9 neutrino mass matrix in this scenario, and surprisingly we find that EDSM will degenerate to a conventional type-I seesaw mechanism when \(M_{\mathrm{R}}= M_{\mathrm{S}}M_{\mu}^{-1}M_{\mathrm{S}}^{T}\) holds exactly. Considering two simple ansätze in two texture zeros for its 3×3 submatrices, we calculate the neutrino masses and flavor mixing angles, in which the θ 13 is a nonzero large angle.
