A search for particles with magnetic charge produced ine+e− annihilations at 543-1543-1543-1GeV

By seeking to identify magnetically charged particles by their trajectories in a magnetic field, we set limits on the production of monopoles and dyons, via the processe+e−→γ*→M\(\bar M\), of masses up to 17 GeV and of magnetic charges between 10 e and 70 e
