In a sample of 670 000 charged-current neutrino events, 101 μ-μ- events have been observed, with 30 GeV<Eν<600 GeV and Pμ>9 GeV/c for both muons. After background subtraction, 18.5±13.9 events remain, yielding a prompt rate of (5.5±4.1)×10-5 per charged-current event. A sample of 124 000 antineutrino events yields 15 μ+μ+ events, giving 6.4±4.2 events after background subtraction and a prompt rate of (1.0±0.7)×10-4 per charged-current event. The numbers and kinematic distributions of these events are consistent with standard model sources.
