A neglected force produced by neutrinos and other particles has helped resolve a long-standing discrepancy in atomic physics measurements, bringing experimental results into alignment with predictions of the Standard Model of particle physics.
Researchers report that the so-called “neutrino force,” a subtle influence transmitted when particles exchange pairs of neutrinos or other fermions, contributes meaningfully to atomic parity violation experiments. When included in theoretical calculations, this force eliminates a persistent tension between observed data and Standard Model predictions.
