Descripción
Sumario:Inverse muon decay, <math display="inline"><msub><mi>ν</mi><mi>μ</mi></msub><msup><mi>e</mi><mo>-</mo></msup><mo stretchy="false">→</mo><msup><mi>μ</mi><mo>-</mo></msup><msub><mi>ν</mi><mi>e</mi></msub></math>, is a reaction whose cross section can be predicted with very small uncertainties. It has a neutrino energy threshold of <math display="inline"><mo>≈</mo><mn>11</mn><mtext> </mtext><mtext> </mtext><mi>GeV</mi></math> and can be used to constrain the high-energy part of the flux in the NuMI neutrino beam. This reaction is the dominant source of events which only contain high-energy muons nearly parallel to the direction of the neutrino beam. We have isolated a sample of hundreds of such events in neutrino and antineutrino enhanced beams, and have constrained the predicted high-energy flux.
