Leptonic first-row correlation and unitarity waiting for further JUNO tests
Zhi-zhong Xing
We conjecture that there exists a remarkable correlation among the three elements in the first row of the lepton flavor mixing matrix : $|U^{}_{e1}|^2 = 2 \left(|U^{…

Emergent large flavor mixing from canonical and inverse seesaws?
Zhi-zhong Xing
While the canonical seesaw mechanism provides a most natural qualitative interpretation of tiny masses for the three active neutrinos, it offers no explanation for their large flav…

On the orthogonal matrix in the Casas-Ibarra parametrization for the Yukawa interactions of Majorana neutrinos
Zhi-zhong Xing
The Casas-Ibarra (CI) parametrization of the Yukawa coupling matrix of Majorana neutrinos is generalized by considering the exact seesaw relation and including non-unitarity of the…
