Five-particle group may disprove string theory, reveal dark matter

Physicists have identified a five-particle group, a "5-plet," that, if detected, could disprove key predictions of string theory and offer clues about dark matter. The study suggests that the absence of this specific particle group within string theory models could be a major limitation, potentially forcing a reevaluation of the theory. The 5-plet includes a Majorana fermion, a potential dark matter candidate. Researchers are now searching for the 5-plet at the Large Hadron Collider, but its heavy mass and quick decay make detection challenging. Future upgrades to the LHC may improve the chances of finding this elusive particle group.
