The reflection symmetry of Dirac neutrinos and its breaking effect via quantum corrections
Zhi-zhong Xing, Di Zhang, Jing-yu Zhu
Given the Dirac neutrino mass term, we explore the constraint conditions which allow the corresponding mass matrix to be invariant under the μ-τreflection transformation, leading u…

The breaking of flavor democracy in the quark sector
Harald Fritzsch, Zhi-zhong Xing, Di Zhang
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. W…
