Query: PASSAT: Particle Accelerator helioScopes for Slim Axion-like-particle
  deTection   We propose a novel method to search for axion-like particles (ALPs) at
particle accelerator experiments (exps). ALPs produced at the target via the
Primakoff effect subsequently enter a region with a magnetic field, where they
are converted to photons that are then detected. Dubbed Particle Accelerator
helioScopes for Slim Axion-like-particle deTection (PASSAT), our proposal uses
the principle of the axion helioscope but replaces ALPs produced in Sun with
those produced in a target material. Since we rely on ALP-photon conversions,
our proposal probes light (slim) ALPs that are otherwise inaccessible to
lab-based exps which rely on ALP decay, and complements astrophysical probes
that are more model-dependent. We first reinterpret existing data from the
NOMAD exp in light of PASSAT, and constrain the parameter space for ALPs
lighter than ~100 eV and ALP-photon coupling larger than ~$10^{-4}$ GeV$^{-1}$.
As benchmarks of feasible low-cost exps improving over the NOMAD limits, we
study the possibility of reusing the magnets of the CAST and the proposed
BabyIAXO exps and placing them at the proposed BDF facility at CERN, along with
some new detectors. We find that these realizations of PASSAT allow for a
direct probe of the parameter space for ALPs lighter than ~100 eV and
ALP-photon coupling larger than ~4 x $10^{-6}$ GeV$^{-1}$, which are regions
that have not been probed yet by exps with lab-produced ALPs. In contrast to
other proposals aiming at detecting 1 or 2-photon only events in hadronic beam
dump environments, that rely heavily on Monte Carlo simulations, the background
(BG) in our proposal can be directly measured in-situ, its suppression
optimized, and the irreducible BG statistically subtracted. Sensitivity studies
with other beams will be the subject of future work. The measurements suggested
here represent an additional physics case for the BDF beyond those already
proposed.
