CP violation within the leptonic sector could provide the path for understanding the observed matter/antimatter asymmetry in the Universe. It has been realised that a non-zero theta13 (mixing angle of the leptonic mixing matrix: PMNS) is necessary to measure the dirac leptonic CP violation through neutrino oscillations. This realisation is embodied by a series experiments designed to measure theta13 within the next 5 years. There are two types of experiments endeavored on this challenge: reactor neutrinos and conventional beam neutrinos. Reactor neutrinos are sensitive to theta13 only, while beam neutrinos are additionally sensitive to the dirac CP violation complex phase inbuilt in the PMNS matrix. Both types of experiments yield, today, comparable sensitivities on theta13. This is not a redundancy but, in fact, an advantage since their results are complementary enhancing the effective sensitivity on CP violation (and other neutrino oscillations observables) through combined analyses. During my seminar, I plan to cover the different experiments having any impact to the hunt for theta13 within the short time scale. This can be through the measurement of Delta_m_square_atmospheric or the theta13 itself. Within this category, I will cover the impact of the following experiments: MINOS (in detail), OPERA, Double Chooz, Daya Bay, RENO, T2K and NOvA. NOTE: I will exclude of my discussion other very interesting experimental approaches such as NuFact, Beta-beams, etc., whose time scale is longer.
