30 Oct 2003 | | Subject: | nucl-th hep-ph | | Abstract: | A model of neutrino oscillation experiments is constructed. The experiments incorporated are: solar neutrinos (Chlorine, Gallium, Super-K, and SNO), reactor neutrinos (Bugey and CHOOZ), beam stop neutrinos (LSND decay at rest and decay in flight), and atmospheric neutrinos. Utilizing this model and the standard three-neutrino mixing extension of the standard model, the data are analyzed. Solutions for the mixing angles and mass-squared differences are found to occur in pairs corresponding to the interchange $Delta m^2_{12} leftrightarrow Delta m^2_{23}$. Two pairs of solutions are found that reasonably reproduce the data, including the LSND data. These solutions are $ heta_{12}approx 0.5$, $ heta_{13}approx 0.1$, $ heta_{23}approx 0.7$, $Delta m^2_{12} approx 5 imes 10^{-5}$ eV$^2$ and $Delta m^2_{23} approx 0.2$ eV$^2$ or 2.4 eV$^2$. Other statistically significant solutions are also found which produce negligible oscillations for the LSND experiments. | | Source: | arXiv, nucl-th/0310083 | | Services: | Forum | Review | PDF | Favorites | |
