Description
The Forward Physics Facility (FPF) is a proposed underground cavern designed to host a suite of far-forward experiments during the Large Hadron Collider High-Luminosity era (LHC-HL). It will sit 627 m downstream from the ATLAS interaction point to exploit the intense flux of high energy collider neutrinos while also searching for beyond standard model (BSM) physics and new particles. The Forward Liquid Argon Experiment (FLArE) is a 30-ton modular Liquid Argon Time Projection Chamber (LArTPC) and one of the primary detectors proposed for the FPF. The LArTPC technology offers a wide dynamic energy range from tens of MeV to hundreds of GeV, making FLArE uniquely suited to a broad physics program within a single detector. FLArE will detect hundreds of thousands of charged-current neutrino interactions across all three flavours, enabling precision measurements of neutrino fluxes and cross sections at multi-hundred GeV energies. These measurements will probe low-$x$ QCD, constrain hadron production models relevant for astroparticle physics, and test non-standard neutrino interactions. FLArE will also search for light dark matter scattering on electrons and argon nuclei with competitive sensitivity in the MeV-to-GeV mass range. This poster presents the physics motivation, the current detector design, and preliminary performance studies for FLArE, including the solutions and detector R&D needed to address the challenges of operating a LArTPC in the high-rate LHC-HL environment.
