Does the KARMEN time anomaly originate from a beam-correlated background?

The time anomaly of neutrino events observed in the KARMEN detector at the ISIS facility is discussed. We show that beam-correlated neutron events are not completely suppressed by the KARMEN lower energy cut and could cause the observed deviation of the measured time distribution from an exponential curve with tau = 2.2 microseconds.Comment: 12 pages including figure captions, 2 figures, 1 tabl
