| contents | It is imperative for us as a particle physics community to fully exploit the physics potential of the High-Luminosity LHC. This calls for us not to leave any stone unturned in the search for Beyond the Standard Model (BSM) physics. Many BSM models that address fundamental questions of physics like the particulate nature of dark matter, the matter-antimatter asymmetry in the Universe, small but non-zero neutrino masses etc, predict Long-Lived Particles (LLPs) with macroscopic lifetimes of $τ>10^{-10}$ s. The challenge in searching for BSM models with LLP signatures at the HL-LHC is that it requires the complementary interplay of general purpose detectors like ATLAS, CMS, and LHCb; dedicated detectors situated close to the beamline including the proposed Forward Physics Facility (FPF); and dedicated detectors covering a large decay volume at a reasonable solid angle transverse to the beamline, i.e., a Transverse Physics Facility (TPF). Hence, it is of vital importance to realise a TPF in order to expand dramatically the physics coverage within long-lived particle searches to harvest the physics at the HL-LHC fully. A TPF may be composed of several experiments based at the HL-LHC. In this document, we propose that the community realise the ANUBIS experiment as part of a TPF. |
