Atmospheric Neutrinos
We examine the possibility of determining the neutrino mass hierarchy in the limit θ13 = 0 using atmospheric neutrinos as the source. In this limit, in which θ13 driven matter effects are absent, independent measurements of ∆31 and ∆32 can, in principle, lead to hierarchy determination. Since the difference between these two is ∆21, one needs an experimental arrangement where ∆21L/E & 1 can be ...
متن کاملAtmospheric 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 کاملUpdate on Atmospheric Neutrinos
We discuss the impact of recent experimental results on the determination of atmospheric neutrino oscillation parameters. We use all published results on atmospheric neutrinos, including the preliminary large statistics data of Super-Kamiokande. We re–analyze the data in terms of both νμ → ντ and νμ → νe channels using new improved calculations of the atmospheric neutrino flux. We compare the s...
متن کاملReview of Atmospheric Neutrinos
In this talk I review measurements and calculations of the flux of neutrinos produced by interactions of cosmic rays in the atmosphere. The main reason for interest in this subject is the apparent anomaly between the predicted and the observed ratio of νe to νμ. With the advent of Super-Kamiokande, we are on the threshold of an order of magnitude increase in the amount of data available to stud...
متن کاملAtmospheric muons and neutrinos
This paper is a mini-review of the atmospheric muon and neutrino flux calculations based upon a recent version of CORT code and up-to-date data on primary cosmic rays and hadronic interactions. A comparison of calculations with a representative set of atmospheric muon data for momenta below ∼ 1 TeV/c is presented. The overall agreement between the calculated muon fluxes and the data provides an...
