González García, Ma. ConcepciónPeña Garay, CarlosSmirnov, Alexei Yu2010-05-062010-05-0620010556-2821https://hdl.handle.net/2445/12510We have performed a detailed study of the zenith angle dependence of the regeneration factor and distributions of events at SNO and SK for different solutions of the solar neutrino problem. In particular, we discuss the oscillatory behavior and the synchronization effect in the distribution for the LMA solution, the parametric peak for the LOW solution, etc. A physical interpretation of the effects is given. We suggest a new binning of events which emphasizes the distinctive features of the zenith angle distributions for the different solutions. We also find the correlations between the integrated day-night asymmetry and the rates of events in different zenith angle bins. The study of these correlations strengthens the identification power of the analysis.18 p.application/pdfeng(c) The American Physical Society, 2001Neutrins solarsPartícules (Física nuclear)Astrofísica nuclearSistema solarSolar neutrinosParticles (Nuclear physics)Nuclear astrophysicsSolar systeminfo:eu-repo/semantics/article551553info:eu-repo/semantics/openAccess
