摘要：

We study finite quantum corrections for several well known neutrino mixing matrices and find that it is hard to account for the large value of theta(13) recently by T2K and MINOS. To nicely reproduce all experimentally favored neutrino mixing angles and masses, we propose a new neutrino mixing pattern. We also demonstrate a simple realization by slightly extending the standard model to illustrate the quantum corrections.
