Future Neutrino Beam Studies Under the Framework of Physics Beyond Colliders

A Physics Beyond Colliders (PBC) initiative was recently established at CERN to exploit the full scientific potential of its accelerator complex and scientific infrastructure to tackle fundamental open questions in particle physics through experiments complementary to those in current and future colliders. This initiative brings together similar studies to optimize resources globally in order to reach a common goal and promote scientific development efficiently. In this work, we present the work performed by the Conventional Beam Working Group (CBWG) and specifically from the Neutrino Beams (NB) subgroup. The subgroup currently deals with two novel neutrino-tagged beams projects, ENUBET and NUTAG, as well as with a more classic, low energy, beamline dedicated to hadron cross-sections for neutrino beams with the NA61 experiment already installed in the H₂ beamline of the CERN North Area. This contribution will detail the advances made with these three projects as well as their status and future plans.
