Getting at large theta_13 with almost maximal theta_23 from tri-bimaximal mixing

Abstract

We introduce a small correction term, ��M_��, in the neutrino sector and examine whether a large ��_13 and an almost maximal ��_23 can simultaneously be obtained starting from the tri-bimaximal neutrino mixing. It is found that one can easily gain ��_13 \simeq 10^\circ, which is favored by the recent T2K experiment, by taking account of the enhancement due to the degeneracy among three neutrino masses. We also find that (��M_��)_22=(��M_��)_33 is a key condition for ��_23 \simeq 45^\circ.
