Limits on like-sign dilepton production in interactions
Abstract
We have searched for the production of like-sign dilepton events (+Ne-+e-+) in a wide-band neutrino beam at Fermilab using the 15-ft bubble chamber. We observe no signal above the background arising from conventional sources. We set 90%-confidence-level upper limits for the production rates of (+Ne-+e-+)(+Ne-+)<~0.76×10-4 and (+Ne-+e-+)(+Ne-+e++)<~5.3×10- 2. © 1985 The American Physical Society.
