Data from RHIC, other experiments nearly rule out role of 'dark photons' as explanation for 'g-2' anomaly

Scientists searching for signs of elusive "dark photons" as an explanation for an anomaly in a groundbreaking physics experiment have nearly ruled out their role. Though the postulated particles could still exist as carriers of a force affecting dark matter, it is increasingly unlikely these particles from the "dark sector" can explain the discrepancy scientists have seen between a precision measurement of the behavior of muons (cousins of more familiar electrons) and calculations based on the reigning theory of particle interactions.
