Abstract
In a sample of 670 000 charged-current neutrino events, 101 events have been observed, with 30 GeV<<600 GeV and >9 GeV/c for both muons. After background subtraction, 18.5±13.9 events remain, yielding a prompt rate of (5.5±4.1)× per charged-current event. A sample of 124 000 antineutrino events yields 15 events, giving 6.4±4.2 events after background subtraction and a prompt rate of (1.0±0.7)× per charged-current event. The numbers and kinematic distributions of these events are consistent with standard model sources.
