“…In order to validate the Monte-Carlo simulation used to compute the experiment sensitivity, the muon flux produced in a small replica of the SHiP target, exposed to the CERN H4 proton beam line, was measured in 2018. The analysis of collected data, corresponding to about 3 × 10 11 protons on target, shows a remarkable agreement with simulation with differences in the absolute rate of the order of 30% for large transverse momenta at high muon momenta [6].…”

The SHiP experiment at CERN has been proposed to search for New Physics at the so-called intensity frontier by probing the existence of very fleebly coupled particles, predicted in several theoretical models, in the few GeV/c 2 mass range. Such hidden particles would be produced in the decays of heavy hadrons from 400 GeV/c proton interactions on a high density target at the Beam Dump Facility to be located in the CERN SPS North Area. Among hidden particles, the search for Heavy Neutral Leptons is very strongly motivated by theory, as they would explain simultaneously the baryon asymmetry of the Universe and the observed neutrino masses. The expected copious production of Ds mesons at the beam dump, producing tau neutrinos through fully leptonic decays, makes SHiP also ideal to study tau neutrino physics with unprecedented sensitivity. The current status of the experiment, recently summarised in the Comprehensive Design Study Report, is presented.

The current status of the proposed SHiP experiment at the CERN Beam Dump Facility is presented. SHiP is a general-purpose fixed-target experiment. The 400 GeV/c proton beam extracted from the SPS will be dumped on a heavy target to integrate 2 × 10 20 protons on target in five years. The detector, based on a long vacuum tank followed by a spectrometer and particle identification detectors, will allow to probe a variety of models with light long-lived exotic particles and masses below O(10) GeV/c 2 . The main focus will be the physics of the so-called hidden portals, i.e. the search for dark photons, light scalars and pseudo-scalars, and heavy neutrinos. The sensitivity to heavy neutrinos will allow to probe, in the mass range between the kaon and the charm meson mass, a coupling range for which baryogenesis and active neutrino masses could also be explained.A second dedicated detector will study neutrinos and explore light dark matter.

“…In order to validate the muon flux generated by the SHiP target, critical for the design of the magnetized muon shield, the SHiP Collaboration installed a small-scale replica of the experiment target in the H4 beam line at the CERN SPS [19]. The experimental setup consisted of a spectrometer equipped with scintillators and drift tubes and a downstream muon tagger, composed of muon detectors interleaved with iron slabs (Figure 4).…”

SHiP (Search for Hidden Particles) is a proposed beam dump experiment at CERN SPS, with the aim of exploring the so-called Hidden Sector. Since a large neutrino flux is expected to be produced at the beam dump, the experiment could also allow for the study of neutrino physics with unprecedented statistics. A dedicated Scattering and Neutrino Detector (SND), equipped with a downstream Muon Identification System, is thus being designed. The SND muon detector consists of iron filters interleaved with tracking planes, based on RPC technology. Each muon plane has an active area of about (2 x 4) m2 and consists of three large gaps read out by two panels of perpendicular strips. The SHiP RPCs have to provide a uniform spatial response as well as high efficiency. The design of the SND muon system is presented and the performance of a SHiP RPC prototype is discussed.
