Abstract

The incredible success of the Standard Model and the absence of clear indications of new physics has sparked a strong interest in "hidden sector" or feebly interacting particles, like dark photons and right-handed neutrinos. The SHiP collaboration has proposed an experiment based on a beam dump at the SPS accelerator at CERN to look for particles in the GeV mass range, able to travel distances of tens of meters. Since a large number of neutrinos will be produced in the beam dump, one of the foreseen sub-detectors is an emulsion tracker to perform precision measurements of tau neutrinos, and direct searches of dark matter. A similar device is the object of a very recent proposal to perform charm measurements from neutrinos in the LHC beam during the LHC Run 3.
