Search for Neutrino like Events 2750 KM from the Source
Abstract
The results are described of a test for the existence of correlations between neutrino telescope events and the accelerator pulses produced by FNAL at 2750 km chord line distance. The beam-off rate was 2.8 sigma below expectation while the beam-on rate was 0.61 sigma above expectation. An excess of beam-on events is found whose probability of being due to chance is 0.06. An excess of events during accelerator active stages is found to be 2.4 sigma above expectation; the probability of this being due to chance is 0.017. The probability that the higher intensity beams associated with the telescope events is due to chance is less than 0.05. The combined probability that all three correlations independently are due to chance is one in 20,000. This result suggests that the observed events are generated by some form of beam particles from the FNAL, a distance of 2750 km from the source.
