Search for Nucleon Decay with Final States l+ eta, nubar eta, and nubar pi+,0 Using Soudan 2
D. Wall
We have searched for nucleon decay into five two-body final states using a 4.4 kiloton-year fiducial exposure of the Soudan 2 iron tracking calorimeter. For proton decay into the f…
Search for nucleon decay into lepton + K0 final states using Soudan 2
The Soudan 2 Collaboration, D. Wall
A search for nucleon decay into two-body final states containing K^0 mesons has been conducted using the 963 metric ton Soudan 2 iron tracking calorimeter. The topologies, ionizati…
The Observation of a Shadow of the Moon in the Underground muon flux in the Soudan 2 detector
The Soudan 2 Collaboration, J. H. Cobb et al
A shadow of the moon, with a statistical significance of 5 sigma, has been observed in the underground muon flux at a depth of 2090 mwe using the Soudan 2 detector. The angular res…
The Atmospheric Neutrino Flavor Ratio from a 3.9 Fiducial Kiloton-Year Exposure of Soudan 2
The Soudan 2 Collaboration, W. W. M. Allison
We report a measurement of the atmospheric neutrino flavor ratio, R, using a sample of quasi-elastic neutrino interactions occurring in an iron medium. The flavor ratio (tracks/sho…
A Study of Cosmic Ray Composition in the Knee Region using Multiple Muon Events in the Soudan 2 Detector
S. M. Kasahara, the Soudan 2 collaboration
Deep underground muon events recorded by the Soudan 2 detector, located at a depth of 2100 meters of water equivalent, have been used to infer the nuclear composition of cosmic ray…
Measurement of the atmospheric neutrino flavour composition in Soudan 2
W. W. M. Allison, G. J. Alner, D. S. Ayres +52
The atmospheric neutrino flavour ratio measured using a 1.52 kton-year exposure of Soudan 2 is found to be 0.72 +- 0.19 +0.05 -0.07 relative to the expected value from a Monte Carl…
