Electron neutrino tagging through tertiary lepton detection

Open Access
Special Article - Tools for Experiment and Theory

Abstract

We discuss an experimental technique aimed at tagging electron neutrinos in multi-GeV artificial sources on an event-by-event basis. It exploits in a novel manner calorimetric and tracking technologies developed in the framework of the LHC experiments and of rare kaon decay searches. The setup is suited for slow-extraction, moderate power beams and it is based on an instrumented decay tunnel equipped with tagging units that intercept secondary and tertiary leptons from the bulk of undecayed π + and protons. We show that the taggers are able to reduce the ν e contamination originating from K e3 decays by about one order of magnitude. Only a limited suppression (∼60%) is achieved for ν e produced by the decay-in-flight of muons; for low beam powers, similar performance as for K e3 can be reached supplementing the tagging system with an instrumented beam dump.
