Measurement of prompt neutrino fluxes in a beam dump experiment

Conference · Sun Feb 01 04:00:00 EST 1981 · AIP Conf. Proc.; (United States)

OSTI ID:6441587

A prompt ..nu../sub ..mu../ flux from a 400 GeV proton beam interacting in a copper dump is observed. The flux of prompt nu-bar/sub ..mu../ in the forward direction is smaller than the ..nu../sub ..mu../ flux. The rate of prompt ..nu../sub e/ production confirms results from the earlier CDHS beam dump experiment. The ratio of prompt ..nu../sub e/ and ..nu../sub ..mu../ fluxes is compatible with unity. Observed energy spectra of the prompt events are in qualitative agreement with charm production and decay.
