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 ...

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.

Atmospheric 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...
