Many particles hypothesized in searches for new physics are theorized to interact feebly with matter.
Notes on verification
Well-corroborated by physics literature including arXiv briefing papers, peer-reviewed journals, and independent encyclopedic sources describing 'Feebly Interacting Particles' as a recognized class in new physics searches.
