英文摘要: We conjecture that all CP violations (both Dirac and Majorana types) arise from a common origin in the neutrino seesaw. With this conceptually attractive and simple conjecture, we deduce that mu-tau breaking shares the common origin with all CP violations. We study the common origin of mu-tau and CP breaking in the Dirac mass matrix of seesaw Lagrangian (with right-handed neutrinos being mu-tau blind), which uniquely leads to inverted mass ordering of light neutrinos. We then predict a very different correlation between the two small mu-tau breaking observables theta(13) - 0 degrees and theta(23) - 45 degrees, which can saturate the present experimental upper limit on theta(13). This will be tested against our previous normal mass-ordering scheme by the ongoing oscillation experiments. We also analyze the correlations of theta(13) with Jarlskog invariant and neutrinoless beta beta-decay observable. From the common origin of CP and mu-tau breaking in the neutrino seesaw, we establish a direct link between the low energy CP violations and the cosmological CP violation for baryon asymmetry. With these we further predict a lower bound on theta(13), supporting the ongoing probes of theta(13) at Daya Bay, Double Chooz, and RENO experiments. Finally, we analyze the general model-independent Z(2) circle times Z(2) symmetry structure of the light neutrino sector, and map it into the seesaw sector, where one of the Z(2)'s corresponds to the mu-tau symmetry Z(2)(mu tau) and another the hidden symmetry Z(2)(s) (revealed in our previous work) which dictates the solar mixing angle theta(12). We derive the physical consequences of this Z(2)(s) and its possible partial violation in the presence of mu-tau breaking (with or without the neutrino seesaw), regarding the theta(12) determination and the correlation between mu-tau breaking observables.
