Search for new neutral particles in π+-proton collisions at 10.5 GeV/c
We report the results of a search for the hadronic production of unexpected, long-lived, neutral particles (such as neutrinos) in 10.5-GeV/c π+-proton interactions. This is done by directly measuring the momentum carried away by gamma rays, K0's, Λ0's, and neutrons and comparing the sum to the total missing neutral momentum. This calorimetric technique allows us to look for anomalous neutral particles in a manner that is independent of any assumptions about their production or decay characteristics. We report results in various reaction channels in the form of limits on the neutral momentum that could be carried away by particles other than the expected gamma rays, K0's, Λ0's, and neutrons. The analysis finds one channel with a possibly significant momentum imbalance that warrants further study. © 1977 The American Physical Society.
