Description
Neutrino tagging is novel method, envisioned by Pontecorvo in the 1970s but never implemented so far. It aims at associating a neutrino interaction with its parent decay (π+->μ+ν), reconstructed with high rate trackers installed in the beamline. These trackers allow to infer the neutrino properties with record precision. For example, the neutrino energy can be measured with sub-percent relative precision. Such performance opens new perspectives for precision neutrino physics.
With the development of high intensity 4D trackers, the implementation of a tagged neutrino beam is becoming feasible. A first tagged neutrino candidate has already been observed using the high intensity 4D tracker of the NA62 experiment, and developments driven by the HL-LHC continue to push the rate limitations.
This seminar will introduce the concept of neutrino tagging, report on its experimental demonstration at NA62, and present the nuSCOPE project, which aims to build a tagged and monitored short-baseline experiment at CERN to improve our knowledge of neutrino interactions. The seminar will conclude with perspectives on possible applications of neutrino tagging to future long-baseline neutrino experiments.
