The Large Hadron Collider May Already Have Detected Hints of Dark Matter

Key Points:

• Physicists have observed unexplained glitches called unidentified falling objects (UFOs) inside the Large Hadron Collider (LHC), believed to be caused by microscopic dust entering the proton beam and causing sudden beam losses.
• Researchers Xunyu Liang and Ariel Zhitnitsky propose that dark matter, specifically hypothetical axion quark nuggets (AQNs), could induce tiny vibrations in the Earth that shake loose dust particles inside the LHC, triggering these beam-loss events.
• Their theory suggests that AQNs passing near the LHC create faint acoustic shock waves that rattle dust into the beam, producing detectable signals that could be identified using the collider's existing beam-loss monitoring systems without additional hardware.
• The researchers encourage reanalysis of past LHC data for correlated UFO events and suggest that other large particle accelerators might also detect such dark matter-induced signals, potentially expanding dark matter research beyond microscopic particles.
• This novel approach, detailed in Physical Review D, could provide new insights into macroscopic dark matter candidates and inspire broader exploration in the field beyond traditional elementary particle models.
