摘要The recent observation of the smallest neutrino mixing angle theta(13) in the Daya Bay and RENO experiments motivates us to examine whether theta(13) similar or equal to 9 degrees at the electroweak scale can be generated from theta(13) = 0 degrees at a superhigh-energy scale via the radiative corrections. We find that it is difficult but not impossible in the minimal supersymmetric standard model, and a relatively large theta(13) may have some nontrivial impacts on the running behaviors of the other two mixing angles and CP-violating phases. In particular, we demonstrate that the CP-violating phases play a crucial role in the evolution of the mixing angles by using the one-loop renormalization-group equations of the Dirac or Majorana neutrinos in the minimal supersymmetric standard model. We also take the correlative neutrino mixing pattern with theta(12) similar or equal to 35.3 degrees, theta(23) = 45 degrees, and theta(13) similar or equal to 9.7 degrees at a presumable flavor symmetry scale as an example to illustrate that the three mixing angles can receive comparably small radiative corrections and thus evolve to their best-fit values at the electroweak scale if the CP-violating phases are properly adjusted.
