Description
SHADOWS (Search for Hidden And Dark Objects With the SPS) is a
proposed proton beam-dump experiment for the search of a large variety
of feeble-interacting particles (FIP) at the CERN SPS. It will exploit the
potential for searches and discoveries at the intensity frontier offered by
the upgrade of the ECN3 beam line.
SHADOWS, will be located off-axis, which allows the optimisation of the
S/B ratio, and will collect data from up to 5x10$^{19}$ protons of 400 GeV on
target in 4 years of operations. The conceived detector, with a
transversal size of 2.5x2.5 m$^2$ and a length of 34 m, offers excellent
tracking and timing performance for the identification and reconstruction
of most of the visible final state of FIP decays.
SHADOWS will allow to explore a large parameter space region of many
FIPs, like light dark scalars, axion-like particles and heavy neutral
leptons, with masses ranging between 0.1 and 10 GeV.
It will be possibly complemented by a dedicated neutrino experiment
(NaNu@SHADOWS) to further extend the physics reach, in particular for
the study of tau-neutrino events.
After a general introduction on the current status of FIP searches, the
talk will describe the SHADOWS detector concept and will focus on the
physics programme of the experiment
