The paper also lists complementary null searches outside this node’s data basis: AGS experiments (E864, E886, E878, E896), NA52 at the SPS, searches in terrestrial matter, and cosmic-ray searches (SLIM), all negative, with future sensitivity expected from lunar-soil samples and space-based detectors.
