That fact suggests that the particles must be more massive than about 0.3 billion electron volts — about a third the mass of a proton — the researchers calculate.

For a monopole with twice the minimum charge, Rajantie and Gould determined that magnetic monopoles must be more massive than about 10 billion electron volts, going by data from collisions of lead nuclei in the Super Proton Synchrotron, a smaller accelerator at CERN.

Measured at the LHC to be more than 130 times heavier than the proton, the Higgs is one of the most massive particles known.

This shift is sensitive to the proton's radius, and muons — which some 200 times more massive than electrons — make it millions of times easier to measure.

They are known as WIMPs (for weakly interacting massive particles), and if they exist, these particles have masses tens or hundreds of times greater than that of a proton but interact so weakly with ordinary matter that they're difficult to detect.
