Ultimately, the team found no evidence that the electron has an electric dipole moment. The measurement lowered the limit on the moment’s strength by a factor of 2.4. That bound implies a lower bound on the mass of any not-yet-observed particles that would violate time-reversal invariance, as lighter particles would exert a bigger effect. That limit is about 3 or 4 teraelectron volts, Cornell says, about a factor of 2 heavier than the LHC can produce.
