Possibility of observing Leptonic CP violation with perturbed Democratic mixing patterns

Abstract

The Daya Bay Collaboration has recently reported the precise measurement of ${\theta }_{13}\simeq 8.8^{\circ }\pm 0.8^{\circ }$ or ${\theta }_{13}\ne 0$ at 5.2 \sigma level. The observed non-zero ${\theta }_{13}$ can be accommodated by some general modifications to the Democratic mixing matrix. Using such matrices we study the possibility of observing non-zero CP violation in the leptonic sector.
