1. Indirect unitarity violation entangled with matter effects in reactor antineutrino oscillations / Li, Yu-Feng ; Xing, Zhi-zhong ; Zhu, Jing-yu
If finite but tiny masses of the three active neutrinos are generated via the canonical seesaw mechanism with three heavy sterile neutrinos, the 3×3 Pontecorvo–Maki–Nakagawa–Sakata neutrino mixing matrix V will not be exactly unitary. [...]

3. The μ - τ reflection symmetry of Dirac neutrinos and its breaking effect via quantum corrections / Xing, Zhi-zhong ; Zhang, Di ; Zhu, Jing-yu
Given the Dirac neutrino mass term, we explore the constraint conditions which allow the corresponding mass matrix to be invariant under the μ - τ reflection transformation, leading us to the phenomenologically favored predictions θ 23 = π /4 and δ = 3 π /2 in the standard parametrization of the 3 × 3 lepton flavor mixing matrix.

4. Looking into analytical approximations for three-flavor neutrino oscillation probabilities in matter / Li, Yu-Feng ; Zhang, Jue ; Zhou, Shun ; Zhu, Jing-yu
Motivated by tremendous progress in neutrino oscillation experiments, we derive a new set of simple and compact formulas for three-flavor neutrino oscillation probabilities in matter of a constant density. [...]

5. Analytical approximations for matter effects on CP violation in the accelerator-based neutrino oscillations with E ≲ 1 GeV / Xing, Zhi-zhong ; Zhu, Jing-yu
Given an accelerator-based neutrino experiment with the beam energy E ≲ 1 GeV, we expand the probabilities of ν μ → ν e and ν ¯ μ → ν ¯ e $$ {\overline{\nu}}_{\mu}\to {\overline{\nu}}_e $$ oscillations in matter in terms of two small quantities Δ 21 / Δ 31 and A/ Δ 31 , where Δ 21 ≡ m 2 2  −  m 1 2 and Δ 31 ≡ m 3 2  −  m 1 2 are the neutrino mass-squared differences, and A measures the strength of terrestrial matter effects.

6. Leptonic unitarity triangles and effective mass triangles of the Majorana neutrinos / Xing, Zhi-zhong ; Zhu, Jing-yu
Given the best-fit results of six neutrino oscillation parameters, we plot the Dirac and Majorana unitarity triangles (UTs) of the 3×3 lepton flavor mixing matrix to show their real shapes in the complex plane. [...]
