Indirect unitarity violation entangled with matter effects in reactor antineutrino oscillations
/ Li, YuFeng ; Xing, Zhizhong ; Zhu, Jingyu
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. [...]

The μ  τ reflection symmetry of Dirac neutrinos and its breaking effect via quantum corrections
/ Xing, Zhizhong ; Zhang, Di ; Zhu, Jingyu
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.

Looking into analytical approximations for threeflavor neutrino oscillation probabilities in matter
/ Li, YuFeng ; Zhang, Jue ; Zhou, Shun ; Zhu, Jingyu
Motivated by tremendous progress in neutrino oscillation experiments, we derive a new set of simple and compact formulas for threeflavor neutrino oscillation probabilities in matter of a constant density. [...]

Analytical approximations for matter effects on CP violation in the acceleratorbased neutrino oscillations with E ≲ 1 GeV
/ Xing, Zhizhong ; Zhu, Jingyu
Given an acceleratorbased 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 masssquared differences, and A measures the strength of terrestrial matter effects.

Leptonic unitarity triangles and effective mass triangles of the Majorana neutrinos

Given the bestfit 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. [...]
