1. Seesaw mirroring between light and heavy Majorana neutrinos with the help of the S 3 reflection symmetry / Xing, Zhi-Zhong ; Zhang, Di
In the canonical seesaw mechanism we require the relevant neutrino mass terms to be invariant under the S 3 charge-conjugation transformations of left- and right-handed neutrino fields. [...]

2. 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.

3. The breaking of flavor democracy in the quark sectorSupported by National Natural Science Foundation of China (11375207) and National Basic Research Program of China (2013CB834300) / Fritzsch, Harald ; Xing, Zhi-Zhong ; Zhang, Di
The democracy of quark flavors is a well-motivated flavor symmetry, but it must be properly broken in order to explain the observed quark mass spectrum and flavor mixing pattern [...]
