Atmospheric neutrinos in Soudan 2
نویسنده
چکیده
allows a measurement which is independent of an absolute ux or exposure calculation. Soudan 2 is an iron calorimeter with di erent experimental systematics from the water Cherenkov detectors and with a di erent geometry and detection technique from from the Frejus experiment. A large veto shield placed against the cavern wall allows the identi cation of particles entering the detector from the interactions of cosmic ray muons in the surrounding rock. We use these \rock" events to show that our low value of R is not due to contamination from such events.

Atmospheric neutrinos
The results of experiments on atmospheric neutrinos are summarized, with the important exception of Su-perkamiokande. The main emphasis is given to the Soudan-2 and MACRO experiments. Both experiments observe atmospheric neutrino anomalies in agreement with νµ → ντ oscillations with maximum mixing. The νµ → νs oscillation is disfavored by the MACRO experiment.
متن کاملDfub 98/22 Atmospheric Neutrinos and Neutrino Oscillations
After some generalities on neutrino oscillations and on neutrinos, the recent experimental results presented by Soudan 2, MACRO and SuperKamiokande at the Neutrino’98 conference are summarized and discussed.
متن کاملAtmospheric Neutrinos and the Oscillations Bonanza
New observations with atmospheric neutrinos from the underground experiments SuperKamiokande, Soudan 2, and MACRO, together with earlier results from Kamiokande and IMB, are reviewed. The most recent observations reconfirm aspects of atmospheric flavor content and of zenith angle distributions which appear anomalous in the context of null oscillations. The anomalous trends, exhibited with high ...
متن کاملNeutrino-oxygen Interactions: Role of Nuclear Physics in the Atmospheric Neutrino Anomaly
The apparent anomaly in the ratio of muon to electron atmospheric neutrinos first observed by Kamiokande and IMB has been confirmed by Super-Kamiokande and Soudan-2. The experimental analysis, including the asymmetry in the zenithal distributions of the μ− type events in Super-Kamiokande gives a strong support to the neutrino oscillation hypothesis to solve the anomaly. In this work we are inte...
متن کاملAtmospheric neutrino data : Active-Active × Active-Sterile oscillations
Atmospheric showers are initiated when primary cosmic rays hit the Earth’s atmosphere. Secondary mesons produced in this collision, mostly pions and kaons, decay and give rise to electron and muon neutrino and anti-neutrinos fluxes [1]. In the past Fréjus and NUSEX [2] reported a R-value (R = (μ/e)data/(μ/e)MC) consistent with one, therefore other detectors like Kamiokande, IMB and Soudan-2 [3]...
