Description
This document presents the NA61/SHINE (and future collaborations based on) physics goals concerning the study of the diagram of high-energy nuclear collisions and the measurements requested by the long-baseline accelerator neutrino experiments in Japan and in the US.
The NA61/SHINE setup has been recently significantly upgraded.
This upgrade opens the possibility to study the nuclear interactions in the energy range $\sqrt{s_{NN}}$ betweeen 5 and 17 GeV, as available for nuclear beams at the CERN SPS, with new observables (e.g. open charm) and with unprecedented data acquisition capabilities.
This energy range touches high-energy part of the scientific program of the CBM Collaboration at future FAIR SIS100 synchrotron and overlaps with the RHIC BES and FXT programs in the PbPb/AuAu mass region only.
The mentioned improvements would allow to contribute significantly to the predictions of the neutrino flux in actual and planned accelerator neutrino experiments (Kamiokande and FNAL), reducing the systematical uncertainty of the primary neutrino beam
