Seminar #4: Con-CERN-ing Neutrinos: One Beam to Tag Them All

Tuesday 22 Apr 2025, 13:00 → 14:00 Europe/Zurich

Lecture Hall (1st Wing)

Monitored neutrino beams have long been proposed as a path toward precise, event-by-event flux measurements—an essential ingredient for reducing cross section uncertainties in future oscillation experiments. The ENUBET project is leading this effort by developing a novel beamline that directly monitors charged leptons produced in meson decays within an instrumented decay tunnel, enabling an unprecedented level of control over the neutrino flux. In this talk, I will present the ENUBET beamline design, its expected performance, and the implications for neutrino cross section measurements. I will also discuss early results from the ENUBET Demonstrator—a prototype of the decay tunne — and how its performance informs the viability of monitored beams in practice. Finally, with the recent proposal submitted to the ESPPU, in collaboration with NuTAG, we will explore the prospects of implementing such a beamline at CERN: a journey through precision instrumentation and beam design... there, and back again..
