Phenomenology of long baseline neutrino oscillation Beta Beam experiments and their related technologies
The primary goal of the future experimental program in neutrino oscillation physics is to determine the size of the unknown mixing angle, $\theta_{13}$, whether CP-violation is present in the leptonic sector and the sign of the atmospheric mass squared splitting. If $\theta_{13}$ is not found by …
