abstract
We present a unique Yukawa structure of the Zee model that can accommodate neutrino oscillation data, solves the muon ${g-2}$ problem, and explains the recent $W$ boson mass measurement. Our Yukawa structure is minimal in the sense that it contains the least possible number of parameters. In this minimal scenario, neutrino masses are quasidegenerate and are compatible with both normal and inverted orderings. The mixing angle $\theta_{23}$ is predicted to lie in the second (first) octant for normal (inverted) ordering. In both cases, the CP violating phase is close to 3$\pi/2$. The minimal texture also predicts a large branching fraction of the heavy neutral Higgs boson into a pair of electron and muon.

Revisiting the two-zero texture Majorana neutrino mass matrix
Five of the seven two-zero texture Majorana neutrino mass matrices are in severe tension with cosmology and neutrinoless double beta decay bounds under a NuFit 6.0 scan, while A1 and A2 remain viable and predict small lightest neutrino masses.
