Atmospheric Neutrino Oscillations
The recent results from the Soudan 2, MACRO and SuperKamiokande experiments on atmospheric neutrino oscillations are summarized and discussed. Some features of possible future atmospheric neutrino experiments are presented.
متن کاملSolar and Atmospheric Neutrino Oscillations
I review the status of neutrino masses and mixings in the light of the solar and atmospheric neutrino data in the framework of two–, three– and four neutrino mixing. 1 Indications for Neutrino Mass: Two–Neutrino Analysis I a first review the present experimental status for solar and atmospheric neutrinos and the results of the different analysis in the framework of two–neutrino oscillations. Th...
متن کاملAtmospheric Neutrino Oscillations in Macro
In this paper we first give a short overview of the MACRO detector which was operational at the Gran Sasso Laboratory from 1989 till the end of 2000. Then we present and discuss the results on atmospheric muon neutrino oscillations, concerning medium (∼ 4 GeV) and high (∼ 50 GeV) energy data. Using the Multiple Coulomb Scattering of muons inside the lower part of the detector, estimates of neut...
متن کاملProblems with Atmospheric Neutrino Oscillations
The neutrino oscillation hypothesis does a poor job of representing the atmospheric neutrino anomaly. The anomaly is observed over 4 decades in path length and at least a factor of 30 in energy. This restricts the potential oscillation solutions to those with large amplitudes and mixing mass differences that are ruled out by other observations. The ∆m2 region in the range 10−4−10−2 leads to inc...
متن کاملDiscovery of Atmospheric Neutrino Oscillations
Neutrinos are a type of fundamental particles, like electrons and quarks. They have no electric charge and they come in three types (flavors), namely the electron neutrino (νe), the muon neutrino (νμ) and the tau neutrino (ντ). They are produced in various places such as in the Earth’s atmosphere and in the center of the Sun. The interactions of neutrinos with matter are so weak that they easil...
