Exact Phenomenology of the Neutrino Cuboid: Normal Mass Ordering, the Tribimaximal Limit, and Cosmological Constraints

Jianlong Lu

We investigate the exact phenomenology of a geometric neutrino cuboid defined by $m_{1} = m_{0} sin I^¾$ , $m_{2} = m_{0} cos I^¾ sin I^¶$ , and $m_{3} = m_{0} cos I^¾ cos I^¶$ , whose cubic point corresponds to…

Exact constraints on family-separated seesaw relations and their phenomenological consequences

Jianlong Lu

Working at tree level and at a common renormalization scale, we examine the family-separated seesaw ansatz of Z.-z.~Xing, arXiv:2605.27049v2. For a fixed light-heavy pairing, impos…

$D_{N}$ -Orthogonal Freedom in the Canonical Seesaw: Flavor Invariants and Physical Non-Equivalence of F-Classes

Jianlong Lu

We study basis-independent structures in the Type-I seesaw mechanism for light Majorana neutrinos, assuming the canonical scenario with three heavy right-handed (sterile) neutrinos…
