Understanding Neutrino Beams for the Precision Era of Neutrino Physics

by Yoshikazu Nagai (Eötvös University, Budapest)

In current measurements of accelerator-based neutrino experiments, neutrino 
flux uncertainties represent a leading systematic uncertainty. Neutrino beams 
are created from the decays of hadrons produced in hadron-nucleus interactions. 
The primary and secondary hadron production processes are the leading source of 
the flux uncertainty of neutrino beams, therefore, precise hadron production 
data are essential to constrain the flux uncertainty. The neutrino program of 
the NA61/SHINE at CERN’s SPS conducts a series of dedicated measurements for 
this purpose.

This talk will first review the current status of accelerator-based neutrino 
experiments, particularly for neutrino flux prediction of the T2K experiment, 
with published NA61/SHINE’s hadron production data. The talk will then review 
the recent news and future plans of the NA61/SHINE’s neutrino program, 
including the possibility to extend the physics program beyond the ongoing data 
taking. Lastly, the talk will briefly discuss the impact of improved flux 
knowledge for the next-generation neutrino experiments and introduce the 
activities of ELTE’s neutrino group towards the goal.
