The KamLAND experiment has determined a precise value for the neutrino oscillation parameter $\Delta m^{2}_{21}$ and stringent constraints on $\theta_{12}$. The exposure to nuclear reactor anti-neutrinos is increased almost fourfold over previous results to 2.44$\times10^{32}$ proton-yr due to longer livetime and an enlarged fiducial volume. An undistorted reactor $\bar{\nu}_{e}$ energy spectrum is now rejected at>5$\sigma$. Extending the analysis down to the inverse beta decay energy threshold…

The reactor neutrino experiment Double Chooz measures the neutrino mixing angle θ13 by means of the Inverse Beta Decay. Within the scope of the present thesis the radioactivity-induced background to
Optimisation of detectors for the golden channel at a neutrino factory
That neutrinos have mass and mix is now well established experimentally. Measurements of the properties of neutrinos from both natural and man-made sources have measured the large mixing angles and
A geometric progression on the mass of elementary fermions
The Standard Model of particle physics contains three generations of elementary fermions, which have prominent mass hierarchies. Through careful analysis of the observational data on the mass of
Mass Distribution of elementary fermions
Through careful analysis of the observational data on the mass of elementary fermions, we determine that an intrinsic pattern does exist. A geometric progression is proposed to describe the mass
