Abstract
We report on the results of the first search for the production of axion-like particles (ALPs) via Primakoff production on nuclear targets, ᵧA → aA, in the "SRC-CT" experiment using the GlueX detector at Jefferson Lab. This search uses an integrated luminosity of 100 pb-1 center dot nucleon on a C-12 target with a real photon beam of energies 6 < Eᵧ < 10.8 GeV, and explores the mass region of 200 < m(a) < 450 MeV via the decay a → ᵧᵧ. This mass range is between the pi0 and η meson masses, which enables the use of the measured η meson production rate to obtain absolute bounds on the ALP production with reduced sensitivity to experimental luminosity and detection efficiency. We find no evidence for an ALP, consistent with previous searches in the quoted mass range, and present limits on the effective photon coupling scale of O(1 TeV-1). We further find that the ALP production limit we obtain is hindered by the peaking structure of the non-target-related dominant background the in GlueX spectrometer, which we treat by using data on 4He to estimate and subtract it. We comment on how this search can be improved in a future higher-statistics dedicated measurement.
