  Gravitational wave detector technology provides high-precision measurement
apparatuses that, if combined with a modulated particle source, have the
potential to measure and constrain particle interactions in a novel way, by
measuring the pressure caused by scattering particle beams off the mirror
material. Such a measurement does not rely on tagging a final state. This
strategy has the potential to allow us to explore novel ways to constrain the
presence of new interactions beyond the Standard Model of Particle Physics and
provide additional constraints to poorly understood cross sections in the
non-perturbative regime of QCD and Nuclear Physics, which are limiting factors
of dark matter and neutrino physics searches. Beyond high-energy physics, if
technically feasible, the proposed method to measure nucleon-nucleon
interactions can lead to practical applications in material and medical
sciences.
