| Abstract | The BDF/SHiP collaboration has proposed a general-purpose intensity-frontier experimental facility operating in beam-dump mode at the CERN SPS accelerator to search for feebly interacting GeV-scale particles and to perform measurements in neutrino physics. CERN is uniquely suited for this programme owing to the proton energy and yield available at the SPS. This puts BDF/SHiP in a unique position worldwide to make a breakthrough in a theoretically and experimentally attractive range of the FIP parameter space that is not accessible to other experiments. The existing ECN3 experimental facility makes it possible to implement BDF at a fraction of the cost of the original proposal, without compromising on the physics scope and the physics reach. SHiP has demonstrated the feasibility to construct a large-scale, versatile discovery experiment capable of coping with $4\times 10^{19}$ protons per year at 400 GeV/c and ensuring a < 1-event background for the FIP decay search even up to $6\times 10^{20}$ PoT. With the feasibility of the facility and the detector proven, the BDF/SHiP collaboration are ready to proceed with the TDR studies and commence implementation in CERN’s Long Shutdown 3. During the operational lifetime of BDF/SHiP, several prominent opportunities for upgrades and extensions are open, such as the use of a LAr TPC, a synergistic tau flavour violation experiment, and exploiting the secondary mixed-field radiation from the proton target for nuclear and astrophysics, as well as for material testing. |
