Low Energy Atmospheric Neutrino Events in MACRO
The flux of low energy atmospheric neutrinos (Eν ∼ 4 GeV ) has been studied with the MACRO detector at Gran Sasso by detecting νμ interactions inside the apparatus, and by upward-going stopping muons. The updated analysis of the data collected until now with the complete apparatus will be presented. The results show a deficit of the measured number of events in an uniform way over the whole zen...
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 کاملAtmospheric neutrino oscillations with MACRO
We present the latest results on the study of atmospheric neutrino oscillations with the MACRO detector at Gran Sasso. Two sub-samples of events have been analysed, both in terms of absolute flux and zenith angle distribution: high energy events (with 〈Eν〉 ≃ 50 GeV) and low energy events (with 〈Eν〉 ≃ 4 GeV). The high energy sample has been used also to check the νμ ↔ νsterile oscillation hypoth...
متن کاملNeutrino-Induced Upward-going Muons at MACRO
Upward-going muon events in MACRO allow measurement of the ux in the range E 10 to 100 GeV. The ratio of total observed to expected events is 0:74 0:036stat 0:046sys 0:13theor, which when combined with the observed zenith angle distribution ( 1:0 cos 0:1) agrees with the no-oscillation model to no better than 0.1%. The data are in signi cantly greater agreement with the $ vacuum oscillation mod...
متن کاملNeutrino Oscillations at High Energy by MACRO
We present updated results of the measurement of upward-going muons produced by neutrino interactions in the rock below the MACRO detector. These data support MACRO’s previously published results. They favor a neutrino oscillation explanation of the atmospheric neutrino anomaly.
