Exact parameter-free sum rules for the Pontecorvo–Maki–Nakagawa–Sakata matrix from a split-and-recombined tribimaximal construction

We present an exact, fixed-input sum-rule construction for the Pontecorvo–Maki–Nakagawa–Sakata (PMNS) matrix: a deterministic ansatz combining a Koide–Brannen square-root mass-ratio input with a discrete split-and-recombined deformation of tribimaximal mixing (TBM), with every mi...

Polarization calibration of spaceborne lidar using dense cirrus–scattered solar background with molecular scattering correction

Abstract. Accurate calibration is essential for spaceborne polarization-sensitive lidars, as biases in depolarization ratio measurements can significantly affect the retrieval of cloud and aerosol properties. A polarization calibration technique based on solar background signals...
