Future Opportunities in Accelerator-based Neutrino Physics

This document summarizes the conclusions of the NeutrinoTown Meeting held at CERN in October 2018 to review the neutrinofield at large with the aim of defining a strategy for accelerator-based neutrinophysics in Europe. The importance of the field across its many complementary components is stressed. Recommendations are presented regarding the accelerator based neutrinophysics, pertinent to the European Strategy for Particle Physics. We address in particular i) the role of CERN and its neutrinoplatform, ii) the importance of ancillary neutrinocross-section experiments, and iii) the capability of fixed target experiments as well as present and future high energy colliders to search for the possible manifestations of neutrino mass generationmechanisms.
